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 PiperIf we cannot claim to live sinless lives, then the only thing that can keep us from despairing before a holy God is that we have an Advocate in heaven and He pleads our case not on the basis of our perfection but of His propitiation.
John PiperWays to be actively involved in the solution: 1. Consider adoption. 2. Be a regular giver of your money to Crisis Pregnancy Centers. 3. Volunteer in a Crisis Pregnancy Center. 4. Be involved in spreading truth with good literature. 5. Make your presence know at the abortion clinics in town (by) writing or phoning or visiting and talking, if you can, with those who work there. 6. Dream a new kind of ministry. 7. Pray!
John PiperIf God were not just, there would be no demand for his Son to suffer and die. And if God were not loving, there would be no willingness for his Son to suffer and die. But God is both just and loving. Therefore his love is willing to meet the demands of his justice.
John PiperWhat is sin? It is the glory of God not honored. The holiness of God not reverenced. The greatness of God not admired. The power of God not praised. The truth of God not sought. The wisdom of God not esteemed. The beauty of God not treasured. The goodness of God not savored. The faithfulness of God not trusted. The commandments of God not obeyed. The justice of God not respected. The wrath of God not feared. The grace of God not cherished. The presence of God not prized. The person of God not loved. That is sin.
