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 PiperGod took the record of all your sins-all your sexual failures-that made you a debtor to wrath, and instead of holding them up in front of your face and using them as the warrant to send you to hell, he put them in the palm of his Sonโs hand and nailed them to the cross.
John PiperOh, how rare are the Christians who speak with a tender heart and have a theological backbone of steel.
John PiperJames says, "You desire and do not have; so you kill" (Jas. 4:2). We kill marriages and we kill unborn babies because they cut across our desires; they stand in the way of our unencumbered self-enhancement. And we live in a culture where self-enhancement and self-advancement is god. And if self-enhancement is god, then the One who is at work in the womb shaping a person in His own image is not God and the assault on His work is not sacrilegious, but obedience to the god of self.
John PiperThe task of all Christian scholarshipโnot just biblical studiesโis to study reality as a manifestation of Godโs glory, to speak and write about it with accuracy, and to savor the beauty of God in it, and to make it serve the good of man. It is an abdication of scholarship when Christians do academic work with little reference to God. If all the universe and everything in it exist by the design of an infinite, personal God, to make his manifold glory known and loved, then to treat any subject without reference to Godโs glory is not scholarship but insurrection.
