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 PiperLove is doing what will enthrall the beloved with the greatest and longest joy. What will enthrall the beloved this way is the glory of God. Love means doing all we can, at whatever cost to ourselves, to help people be enthralled with the glory of God. When they are, they are satisfied and God is glorified. Therefore loving people and glorifying God are one.
John PiperI have tried to devote my life - with all my husband failures, father failures, pastor failures, friend failures, any other possible failures I'm sure I've done them - to the God-centeredness of God and my aspiring, yearning to join Him in that activity. God is passionate about hallowing the name of God.
