Sin is no longer your master, for you no longer live under the requirements of the law. Instead, you live under the freedom of God’s grace. Well then, since God’s grace has set us free from the law, does that mean we can go on sinning? Of course not!
Rom. 6:14-15 NLT
Grace is not the freedom to sin, but the freedom not to sin. Grace is a mighty force: Jesus in us freely bestowing to us his power for victory over sin. Jesus being grace is available at any time, in any place, and for any situation to strengthen us to walk apart from the selfishness and destructiveness of sin (2 Cor. 9:8). Grace comes and quenches our sinful desires and extinguishes our immoral passions.
I believe there is not a single desire of the heart that is known to a man to exist, which may not be completely quenched by the grace of God that is given us through Jesus Christ, if that appetite or desire or taste be contrary to the mind or will of God.
I believe the grace of God is able so to put forward the blessed Lord Jesus Christ, so to exhibit the beauty of the Savior, so to attract the heart and the will and the feelings of a man, that he can look up into the face of the Lord Jesus as the sweetest and all-absorbing thing, so that the man has no room for naughty appetite or desire.
