Born Captive to Sin, Rescued by Grace

I was born into this world with certain sinful dispositions and inclinations, and neither therapy nor willpower could produce real change to my fallen human nature. God's holy laws could only expose to me, as a fallen creature, my utter moral impotence and accountability to God (Rom 3:19, 20) but gave me no ability to obey them. The gospel, on the other hand, is not a simple call to behavior modification, but instead, the granting of a renewed heart, a new nature, which loves God's commands (1 John 3:9, 5:1-4; Deut 30:6; Ps. 119:97; Ezek 36:26). And by grace I was declared righteous for Jesus's sake, who fulfilled God's law for me, not because I brought anything of my own to the table. As a result the gospel of grace awakens me to the fact that other sinners are also fallen human beings. So how can I look down on anyone, when God had such amazing mercy on a great sinner like me? I now only want to point others to the light of the gospel of Christ that they might also know Him.
