Sin is what you do when your heart is not satisfied with God. No one sins out of duty. We sin because it holds out some promise of happiness. That promise enslaves us until we believe that God is more to be desired than life itself (Psalm 63:3). Which means that the power of sin's promise is broken by the power of God's.

John PiperThe greatest cause in the world is joyfully rescuing people from hell, meeting their earthly needs, making them glad in God, and doing it with a kind, serious pleasure that makes Christ look like the Treasure he is.
John PiperThe main reason God has given us minds is that we might seek out and find all the reasons that exist for treasuring him in all things and above all things.
John PiperPastors and missionaries (need) to know God and to find in him a Treasure more satisfying than any other person or thing or relationship or experience or accomplishment in the world.
