God’s grace in Christ does more than forgive the guilt of sin, it also breaks the power of sin.
"By this we know that we love the children of God, when we love God and observe His commandments. 3 For this is the love of God, that we keep His commandments; and His commandments are NOT BURDENSOME. 4 For whatever is born of God overcomes the world; and this is the victory that has overcome the world—our faith." 1 John 5:2-4
"We know that our old sinful selves were crucified with Christ so that sin might lose its power in our lives. We are no longer slaves to sin. For when we died with Christ we were set free from the power of sin." Romans 6:6-7
"Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life." 2 Corinthians 3:6,
"For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 1 Corinthians 1:18
