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 PiperMy mother, who grew up in Pennsylvania, literally washed my mouth out with soap once for saying, 'Shut up!' to my sister. She would have washed my mouth out with gasoline if she knew how foul my mouth was racially when she wasn't around.
John PiperGrace is the pleasure of God to magnify the worth of God by giving sinners the right and power to delight in God without obscuring the glory of God.
John PiperThe greatest stumbling block for children in worship is that their parents do not cherish the hour. Children can feel the difference between duty and delight. Therefore, the first and most important job of a parent is to fall in love with the worship of God. You can't impart what you don't possess.
John Piper
