Suffering in the path of Christian obedience, with joy - because the steadfast love of the Lord is better than life (Psalm 63:3) - is the clearest display of the worth of God in our lives. Therefore, faith-filled suffering is essential in this world for the most intense, authentic worship. When we are most satisfied with God in suffering, he will be most glorified in us in worship. Our problem is not styles of music. Our problem is styles of life. When we embrace more affliction for the worth of Christ, there will be more fruit in the worship of Christ.
John PiperThe root cause of abortion is the failure to be satisfied in God as our supreme love. And, for all the great legal work that needs to be done to protect human life, the greatest work that needs to be done is to spread a passion - a satisfaction for the supremacy of God in all things. That's our calling.
John PiperAdjust your doctrine - or just minimize doctrine - to attract the world, and in the very process of attracting them, lose the radical truth that alone can set them free.
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.
