It is not saving faith to confess Christ as true. Saving faith receives Christ as a Treasure.
John PiperWhere the Bible is esteemed as the inspired and inerrant Word of God, preaching can flourish. But where the Bible is treated merely as a record of valuable religious insight, preaching dies.
John PiperAnger devours almost all other good emotions. It deadens the soul. It numbs the heart to joy and gratitude and hope and tenderness and compassion and kindness.
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.
