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.
John PiperLife is not a straight line leading from one blessing to the next and then finally to heaven. Life is a winding and troubled road. Switchback after switchback. And the point of biblical stories like Joseph and Job and Esther and Ruth is to help us feel in our bones (not just know in our heads) that God is for us in all these strange turns. God is not just showing up after the trouble and cleaning it up. He is plotting the course and managing the troubles with far-reaching purposes for our good and for the glory of Jesus Christ.
John PiperThe way of the cross is the way of suffering. Christians are called to die, not kill, in order to show the world how they are loved by Christ.
John PiperSin 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.
