Understanding this has changed me. Profoundly.

The key to winning the battles over sin in your life in the long term is not found in some inner reservoir of strength or new-found resolve. Instead, it is found in the joy and freedom of the Gospel. When you have tasted the goodness of God and freedom from guilt and shame, it puts your mouth out of taste for the fleeting and corrupting pleasure of sin. Turn to God for forgiveness, and believe that Jesus' death was for YOU. Sin promises lasting joy, but only delivers short-term pleasure. Like bait on a hook. God is infinitely more satisfying.
