If God is not supreme in our preaching, where in this world will the people hear about the supremacy of God? If we do not spread a banquet of God’s beauty on Sunday morning, will not our people seek in vain to satisfy their inconsolable longing with the cotton candy pleasures of pastimes and religious hype? If the fountain of living water does not flow from the mountain of God’s sovereign grace on Sunday morning, will not the people hew for themselves cisterns on Monday, broken cisterns that can hold no water ?  – John Piper
