1 Adam lay with his wife Eve, and she became pregnant and gave birth to Cain. She said, “With the help of the Lord I have brought forth a man.” 2 Later she gave birth to his brother Abel. Now Abel kept flocks, and Cain worked the soil. 3 In the course of time Cain brought some of the fruits of the soil as an offering to the Lord. 4 But Abel brought fat portions from some of the firstborn of his flock.
The Lord looked with favor on Abel and his offering, 5 but on Cain and his offering he did not look with favor. So Cain was very angry, and his face was downcast. 6 Then the Lord said to Cain, “Why are you angry? Why is your face downcast? 7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it.”
8 Now Cain said to his brother Abel, “Let’s go out to the field.” And while they were in the field, Cain attacked his brother Abel and killed him. 9 Then the Lord said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?” 10 The Lord said, “What have you done? Listen! Your brother’s blood cries out to me from the ground.” – Genesis 4:1-10
We’re looking at the storyline of the Bible. We’re saying each week that the Bible is not primarily a set of disconnected individual stories, each of which has a little lesson or moral about how to live life, but primarily, the Bible is a single storyline, a single story, that tells us what’s wrong with the human race, what God is doing about it, and how history is going to turn out at the end. We’ve begun to trace out this storyline by starting with Genesis, the first four chapters.
The Bible’s simple answer to the question, “What’s wrong with the human race?” is sin. Contemporary people just cringe and wince and get a tic when we use the word sin because we don’t like it. Recently I actually read a book review (kind of an older book review but not too old) in the London Times. It was the London Times online. As an offhanded comment, the reviewer said, “You know, we need to retire these words sin and evil. They’re empty and obsolete.”
Okay, then what vocabulary will you use to talk about war atrocities or massive corruption in government and business or slavery or violence? What will you use? What language will you use? Will you use the language of technology or sociology or psychology? Will you talk about maladaptive behavior or dysfunction? That’s not sufficient.
The language we have in those disciplines isn’t profound enough and rich enough to deal with the realities of what’s really going on in the world and what’s wrong with the world. We have to recover the vocabulary of sin. That’s one of the things we’re doing as we look here at Genesis 3 and 4.
Tonight we learn more about what the Bible means by this term sin by looking at this sad and poignant narrative, famous story of Cain and Abel. Let’s look at three new things we learn tonight about what the Bible says is wrong with us and, therefore, three new things about sin. Let’s notice the potency of sin, the subtlety of it, and we see a foreshadowing of the victory over it. So let’s notice the potency of it, the subtlety of it, and our eventual victory over it (all in this text).
1. The potency of it
In verse 7, God, in speaking to Cain, uses a remarkable image. He says, “But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it.” It’s a remarkable image. It’s the image of a leopard or a tiger, a predatory animal, crouching in the shadows, coiled and ready to spring and kill.
God says that’s sin. Sin is predatory. Sin has a deadly life of its own. How is that? Here right away we’re going to see why there is no other set of vocabulary words that we have that deal with the reality of what sin is. How so? First of all, when God uses this image, it’s telling us that sin has an abiding, growing presence in your life. If you commit sin, sin is not over. Sin is not simply an action. It’s a force. It’s a power.
When you do sin, it’s not now over, but it actually becomes a presence in your life. It takes shape, a shadow shape, and stays with you and begins to affect you. Eventually, it can just take you out. You say, “Well, how could that be?” Well, you can start with the psychological concept of habit. You can start there, but you can’t end there. You can start by noticing the things we do become easier to do again and easier to do again and easier to do again and harder to stop doing.
C.S. Lewis some years ago wrote this passage in one of his chapters of Mere Christianity. He says, “That explains what always used to puzzle me about Christian writers; they seem to be so very strict at one moment and so very free and easy at another. They talk about mere sins of thought as if they were immensely important: and then they talk about the most frightful murders and treacheries as if you had only got to repent and all would be forgiven.
But I have come to see that they are right. what they are always thinking of is the mark which the action leaves on that tiny central self which no one sees … but which each of us will have to endure—or enjoy—forever. One man may be so placed that his anger sheds the blood of thousands, and another so placed that however angry he gets he will only be laughed at.”
Do you hear that? Here are two people. They both get angry. One of them, because of the conditions, has the power to kill people with it. The other person, no matter how angry he gets, people just laugh at him. Each has done a little mark on the soul. It’s pretty much the same case in both men.
“Each has done something to himself which, unless he repents, will make it harder for him to keep out of the rage next time he is tempted, and will make the rage worse when he does fall into it. Each of them, if he seriously turns to God, can have that twist in the central man straightened out again: each is, in the long run, doomed if he will not. The bigness or smallness of the thing, seen from the outside, is not what really matters.”
There’s another place, by the way, nearby in Mere Christianity where Lewis makes the interesting observation that first, the Nazis killed the Jews because they hated them. After awhile, they hated the Jews because they had killed them. Here’s the point. When you sin, the sin doesn’t just go away. The sin becomes a presence in your life. You start by doing sin, but then sin does you.
You can decide, “I’m not going to forgive my mother, I’m not going to forgive my father, for what he or she has done.” Okay, you’ve done it, but then it will do you, because that will poison your relationships with other people, certain people in all kinds of ways you don’t even see. It will harden you. Do you see the difference already in this family? When God comes to Adam and Eve (remember last week if you were here) and God says, “What have you done,” at least they’re kind of abashed and sheepish.
Adam is saying, “My wife made me do it.” The wife says, “The Serpent made me do it.” But here God comes to Cain and says, “What have you done?” He says, “Do you think I’m supposed to keep tabs on that guy?” There’s a hardening. First, you start to do sin, and then sin does you. It becomes a presence in your life.
See, it’s not just inside. It’s not just that you … This is the reason why legal terminology is not enough just to say, “We’re violating God’s norms,” nor is psychological terminology quite enough to say, “Well, it creates bad habits or psychological problems.” No, let me go a little further. When it talks about sin as a crouching tiger (or hidden dragon), when it talks about sin like that, it says, for example, in Galatians 6, sins will find you out. You reap what you sow.
Do you know what that means? Sin also creates a presence not just in you but around you. Why? It sets up strains in the fabric of things, the way God made the world, especially in the human community. Haters tend to be hated. Cowards tend to be deserted. He who lives by the sword will die by the sword. What is all that?
When you sin, that sin becomes a presence in your life. It takes shape in and around you, and it will take you out. Therefore, you should avoid sin like the plague, because it is a plague. Somebody says to you, “You know, you have a cancerous tumor growing in this part of your body.” You say, “Well, one of these years I’ll get to it.” You don’t do that. For somebody to come along and say, “You have an abrasive spirit,” or, “You can’t control yourself in this area,” or, “You have this,” or, “You have that character flaw,” you don’t say, “Well, yeah.”
Don’t you dare, because that’s the second aspect of potency we see in this image. The idea of sin crouching at the door not only tells us it’s coiled to spring (it’s a presence in your life that when you sin, you create a presence in your life that then can take you out), but also the image gets across the fact that sin hides.
See, the lion, the tiger, the leopard is crouching. That means down away out of your sight. Why? Because if you see a crouching tiger, you have a chance. You can get a couple of steps on it, but if you don’t see a crouching tiger, you’re dead. If you don’t see it well or you don’t know quite where it’s located … The less aware you are of the location or the reality of the crouching animal, the more vulnerable you are, and the more likely you are to die.
What that means is the worst things in your life, the character flaws and the sins in your life that are most going to ruin you or are ruining you or are going to make the people around you miserable are the things, the character flaws, you least will admit. They’re the ones you’re in denial about, you rationalize, and you minimize. Whatever the consequences happen to you, when somebody brings them up, you rationalize them.
By definition, those are the crouching sins in your life (the ones that are going to take you out). As long as you look at workaholism as conscientiousness, as long as you look at your grudge as moral outrage, as long as you look at materialism as ambition or arrogance as healthy self-assertion, as long as you look at your obsession with looks as good grooming, you’re vulnerable. You’re in denial.
What are the crouching sins in your life? Do you not have a short list of character flaws you know have power over you but you always tend to rationalize, you always tend to minimize? You know, many of us get at least to this spot. We know we’re bad at that. We know that’s a problem for us, and yet when anyone ever brings up an actual particular case of it, “Oh no! You don’t understand.”
At least you know there’s a crouching tiger in there somewhere. You just don’t quite know where. Do you know what your sins are? Do you know what your besetting sins are? Do you know what your crouching sins are? If you don’t even have a list, then you’ve been mastered. So see the potency of sin. See how deadly it is. See why it’s nothing to take lightly. It’s nothing to be trifled with. Okay, now secondly, let’s notice …
2. The subtlety of sin
This brilliant narrative shows us how subtle it is, because here you have Cain, and here you have Abel. We have Abel being accepted by God and Cain being rejected. So what do they represent? They represent the people who call on God’s name and find favor with God and then the people who God rejects.
When you actually read through the narrative, it’s difficult to know why, isn’t it? See, that’s part of the brilliance of the narrative, because we don’t have … Look. Liberals and conservatives basically … When they divide the world into good and bad people, they have this nice, bright line. I think the traditional idea is good people are the people who uphold moral values, and bad people are the people who don’t believe anything, and they live any way they want.
The liberal bright line is good people are the people who are working for inclusion and who are working for a pluralistic society and equality. Bad people are the intolerant people, the fundamentalists, the bigots. I mean, they have these nice lines, but here you have … Look. You don’t see Cain and Abel … One of them is running around boozing it up and womanizing, and the other one is going to church and bringing their offerings.
You don’t see one person working hard, and the other person a ne’er-do-well living off welfare. That’s not what you have. What do you have? The only difference is one seems to be a farmer and one seems to be a rancher, from what we can tell. One is raising animals. To make an offering to God, you bring the firstfruit of the new animals born to you this year, because that’s your income. The other one is a farmer. What you do is you bring some of the produce of your field because that’s your income.
Well, they’re both offering up to God, are they not? They’re both doing God’s will. They’re both seeking God. So what’s the problem? All we’re told is God blessed and showed favor to Abel, which probably almost certainly means he prospered him and made him successful and let things go well in his life, and he didn’t favor Cain. Why? What’s going on? It’s subtle. It’s supposed to be subtle. It’s supposed to be a matter of the heart.
That’s how the narrative gets you to start to investigate. Here are some clues to the answer. The first clue is this. Do you see what it says? It says, “Cain brought some of the fruits of the soil as an offering … But Abel brought fat portions from some of the firstborn of his flock.” Here’s what’s interesting. Every year, the income of a rancher basically is how many more calves and colts and lambs and that sort of thing are being born.
If you want to be really cagey, you wait and give the Lord his offering after you see how many animals are being born to you, right? I mean, if you’re going to have 12 animals born, then, “Oh, I’ll send the Lord one or two.” You know? “I’m a tither. I’ll send three, a little more than a tithe.” Here’s the danger. If you send the first one born, what if there are only two this year? What if there are only three? “I don’t want to give God 50 percent. That’s kind of exorbitant, don’t you think?”
Therefore, there’s a kind of person who is pretty calculating and is “absolutely making sure I give God just what I have to.” Then there’s a kind of person who is openhearted. They’re not calculating. There’s a joy. There’s an abandon. There’s a trust. So we see that in Abel. Do you recognize that? We see a different kind of spirit there, a different level of commitment, a kind of joy, a kind of freedom. You don’t see it in Cain.
Well, where was that? Why? Okay, secondly, Hebrews 11, looking back on this passage … In Hebrews 11, we’re told Abel made his sacrifice and offering in faith, but Cain did not. Well, what the heck does that mean? That’s a little difficult to understand. Why? Well, when you and I think of faith in God, are we saying Cain didn’t have faith in God? You don’t think Cain believed God existed?
I think he believed God existed. He is talking with God here, so that’s not a problem. He really knows God exists. What’s going on? You have to remember from last week God hasn’t given this first family a whole lot of information yet about how he is going to save the world. He has just given them one verse. It’s Genesis 3:15. In Genesis 3:15, God promised one of the descendants of Adam and Eve is going to crush the Serpent’s head, is going to destroy sin and death.
Therefore, God promises to save the world. That’s all we know. It’s pretty vague. It’s awfully rudimentary, but this is what I want you to consider. There are only two reasons you can possibly bring an offering to God. There are only two reasons to put money in the plate. There are only two reasons to bring a lamb or an offering in the Old Testament and New Testament. It doesn’t matter. There are only two reasons to give God an offering.
One is to give God an offering in response to salvation, in gratitude toward salvation. The other reason is to do it as a means of salvation, as a way of getting God to bless you, as a way of getting God to reward you, answer your prayers, take you to heaven. There are only two possible reasons. Even in the rudimentary form that the gospel existed in Abel’s mind, Abel, in some way, was putting his trust in God’s promise of salvation.
As a result, there was an openheartedness about him. There was a lack of calculation. Here’s what happens with Cain. Do you not remember (if you were here in the fall) the parable of the prodigal son and the elder brother and what the elder brother’s heart was like? We said back then … If you weren’t here, don’t worry. I’ll give you the nutshell version of it. If you believe you’re a sinner saved by grace, then everything is gravy. You believe God has saved you in spite of your merits, and everything God gives you is gravy. Everything is icing.
But if you’re an elder brother, if you believe, “God owes me because I’ve worked so hard, and I’ve served my father, and I’ve obeyed the Bible, and I’ve done everything right. God owes me it,” if you believe you’re saved by works, if you believe you’ve put God in your debt … The way you know you’re a sinner saved by grace or an elder brother saved by works is that when God doesn’t let your life go the way you think it ought to go, when God is not blessing you and prospering you and having things go well, the elder brothers get absolutely furious.
Why? It proves they actually believe God owes them because of their good works, because of their offerings. When you see Cain looking first at Abel and seeing Abel being blessed over himself, he is murderously angry, and he is angry at God. He is so angry at God, he is willing to say, “Am I my brother’s keeper?” “Get out of my face.”
What do we have there? You don’t see the difference between Cain and Abel on the surface, do you? They’re both hardworking. They’re both going to church, as it were. They’re both trying to do God’s will, but what is the fundamental trust of their heart? Are they looking to other things or themselves for their salvation, or are they looking to God? That makes all the difference between whether you’re a grumpy, angry, furious Cain, always mad with how the world is going, always upset because somebody is getting ahead of you, competitive, looking at the Abels around …
“Why are they getting ahead? They don’t deserve to be ahead. What’s going on here?” Do you want to be a Cain, or do you want to be an Abel? See, Cains hate Abels. Abels don’t hate Cains. Cains denounce. Cains demonize. Cains are always comparing. Cains are always grumpy. Cains are always anxious. It all has to do with what are you looking to as your salvation? What is your heart’s fundamental trust?
Do you see the subtlety of it? That’s the very essence of whether sin is mastering you or whether you are mastering sin. There’s the potency of sin, and there is the subtlety of sin. Is there any hope? “Preacher, is there any hope?” Well, you know, it’s a sad story. Of course, the story seems to end … There’s no happy ending.
“Then the Lord said to Cain, ‘Where is your brother Abel?’ […] The Lord said, ‘What have you done? Listen! Your brother’s blood cries out to me from the ground.’ ” Yet because this is such a brilliant narrative, it’s such a brilliant text, because the author ultimately was the Holy Spirit, and the Holy Spirit is an incredible storyteller, we have foreshadowing. Right there at the very end, you actually have the basic furniture for …
3. The eventual victory over sin
What do you see? You see two things about God. One is his grace, and one is his justice. First of all, notice his grace. He is asking questions. Again! Remember last week, if you were here? Last week, God does not show up after Adam and Eve sinned and say, “How dare you do what I told you not to do!” Instead, he comes and says, “What have you done? Where have you been? What’s going on?” Even here, he shows up even after the murder and says, “Where is your brother Abel?”
Now look. When God asks you a question, I can guarantee one thing. He is not looking for information. If God is asking you a question, he is not trying to understand your heart. He already understands your heart. He is not trying to figure out what’s going on. He already knows what’s going on.
If God asks you a question, he is trying to get you to understand your heart. He is trying to bring you along. I think in Genesis 3 and 4 one of the most moving things as I’ve meditated on these texts for years now is that God does not show up and say the first time to Cain, “How dare you question who I bless and who I don’t bless! I mean, don’t you know who I am? Who do you think you are? I will have mercy on whom I will have mercy.” He doesn’t do that.
He says to Cain, “I see you’re downcast.” Literally, by the way, God says, “Your face has fallen,” which is actually a Hebrew idiomatic expression for depression. He is coming, and he is counseling a depressed man. He is asking him questions. He is pursuing him, and he is trying to get him to understand his own heart. Look at the tenderness of it.
What amazes me is how, even though he is telling him the truth, he says, “Look, Cain. It’s not Abel’s fault you’re depressed, and it’s not my fault. It’s your own actions and your own attitudes.” Yet he says, “But sin is going to master you. I don’t want it to master you.” Isn’t that amazing? He is coming after Cain. He doesn’t want to see him perish. So there we see the grace of God. There we see the love of God, but at the very same time, in verse 10, we see something.
It’s always kind of spine tingling to me when he says, “Your brother’s blood cries out to me from the ground.” What does that mean? All through the Bible, there are places where God says, “The innocent shed blood is crying to me from the ground.” What does that mean? God is a God of justice. It means when injustice is done, it cries to God, as it were. There’s an outcry.
When there’s violence in Sodom and Gomorrah, he comes by in Genesis 18, and he says to Abraham, “I’m on my way down to Sodom and Gomorrah because of the outcry, the cry of the oppressed, because of the violence, and because of the terrible things that are happening there.” God can’t shrug at sin. He just can’t let it go. He is a righteous God. He is a just God. Injustices cry to him all the time. Innocent shed blood always cries to him for rectification, for making it right. He can’t deny that. He can’t just turn away from that.
Here you have an absolutely just God, and yet an absolutely loving and gracious God. How in the world can a just God save us? He wants to save us, but he is just. How will he ever be able to make good on his promise of Genesis 3:15 to save the world, to save us like this? Here’s how he can be both just and gracious.
Years later, another Man showed up who was a lot like Abel, because he came into a world, he came into a nation, filled with Cains, people who were religiously very observant, who were always bringing their offerings, honoring the sacrificial system, and yet they hated his Spirit, and they slew him. The book of Hebrews says when Jesus Christ shed his blood, an innocent victim of injustice, his blood cried out, but in a new way.
See, this is in Hebrews 12. The writer to the Hebrews says, “You have come to God, the judge of all men, to the spirits of righteous men made perfect, to Jesus the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.” That’s interesting. What is that talking about? Here’s what it’s talking about.
Jesus Christ was, in a sense, the ultimate Abel because he was the only person who was truly innocent who came into this world. He was not a grumpy Cain. He was beautiful. He was gorgeous. He was loving. The Cains couldn’t stand it, and they killed him. But he didn’t die only as a victim of injustice. He also died by design. He died in our place. He died to pay the penalty for our injustices.
Do you know what that means? Let me be as personal as I can possibly be. In the first three or four years of my Christian life, every time I went to God to ask for forgiveness, I was nervous. In fact, when I got up off of my knees when I was done confessing my sins, I was still nervous because I would take 1 John 1:9, where it says, “If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.” and I’d say, “Okay. I’ve sinned, and so I’ll kneel down, and I’ll ask for God’s forgiveness.”
But do you know what? I would sin, and I’d say, “I’ll never do this again.” A few days or weeks later, I had done it again. I’d get down on my knees. A few days or weeks later, I’d done it again. I’d get down on my knees. Every time I would say, “Please be merciful. Please be merciful!” There was something in the back of my head that kept saying, “Okay. You’re in your early twenties. What if you’re still doing this in your early forties, your early fifties? Where will God finally say, ‘Hey, I’m under no obligation to be merciful to you infinitely’?”
Every time I would get up, I would wonder, “Will he be back in my life? Will he bless me?” Then one day I understood what Hebrews 12 was talking about when it says Jesus Christ’s blood speaks a better word than the blood of Abel. Jesus Christ’s blood, like all innocent blood, is crying out for justice, but now what is it saying?
In a sense, Jesus Christ is standing before the throne of his Father and saying, “Father, your law demands justice. These people here have sinned. The wages of sin is death. But for all the people who believe in me, I have paid for it. There is my blood crying out for justice.” Here’s how it cries now. “Justice demands that you never condemn my brothers and sisters.”
Everyone who believes in Jesus Christ and who says, “Father, forgive me because Jesus Christ has died in my place,” do you know what that means? God can never condemn us. Why? Because that would be to get two payments for the same sin, and that would be unjust. That’s the reason why 1 John 1:9, does not say, “If you confess your sins, he is faithful and merciful to forgive us our sins and cleanse us of all unrighteousness.” It says, “… he is faithful and just …” What does that mean?
A life-changing sermon for me was a sermon by David Martyn Lloyd-Jones that I read years ago on 1 John 1:8 and 9. Here’s what he said: If Jesus Christ has shed his blood for you and you have asked God to forgive you because of Jesus Christ’s shed blood, God could never, ever, ever condemn you, because that would be to get two payments, and that would be unjust. Therefore, the justice of God now demands that there is no condemnation for you as long as you live and that you will never perish.
Jesus Christ, in a sense, is not standing before God interceding for us by asking for mercy, because, you see, Jesus is not actually getting up there saying, “Here’s Tim Keller, and he sinned again. So, Father, give him one more chance. Please be merciful one more time.” God is up there saying, “Well, all right.” No wonder I never felt good when I got up off my knees. Now I realize what Jesus Christ essentially is doing.
He is saying, “Tim Keller sinned again, but I’m not asking for mercy. I’m not asking for mercy. I’m demanding justice. Embrace him. Cleanse him. Open his eyes. Come into his life.” The justice of God is infallible. The justice of God is like the mountains. The justice of God and the righteousness of God cannot be gainsaid. Now it’s on our side if you believe in him. See, now the blood of Jesus Christ cries out for justice, but the justice is not against us anymore. It’s for us … all of it.
If you really know you’re that secure in his love, if that moves you to the depths, it shakes you to the depths and it moves you to tears, you’re not going to be a grumpy Cain anymore. You’re not going to always be comparing yourself to other people. You’re not going to be angry because somebody is getting ahead of you. Your identity is not based on your performance anymore and all that kind of thing.
There will be a security. There will be a poise. You’ll become a sweet, loving Abel, not a grumpy, condemning, self-righteous Cain. Don’t you want that? The world needs a lot of Abels. The Cains are out there killing each other, exploiting each other, lying about each other, elbowing each other out.
They’re as miserable as can be. Sin is mastering them, but use this potent gospel of the grace of God to deal with the potent sin in our lives, in your life. The blood of Jesus Christ cleanses from all unrighteousness. Go and learn what that means. Spend the rest of your life learning what that means. Let’s pray.
Father, we thank you that you have given us this great gospel. As sad as it is to see the blood of Abel crying out from the ground for justice, how remarkable it is that it points us to the blood of Jesus Christ crying out that now there can be no condemnation for those who are in Christ Jesus. Oh my! Would you give us a sense of our security? Would you give us a glorious sense of it? Let that reality be the one that controls us. Let it turn us more and more into the Spirit and the image of your Son, Jesus Christ, who did all this for us. It’s in his name we pray, amen.
