Quoted in John Piper, Supremacy of God in Preaching, 109:
The enjoyment of God is the only happiness with which our souls can be satisfied. To go to heaven, fully to enjoy God, is infinitely better than the most pleasant accommodations here. Fathers and mothers, husbands, wives, or children, or the company of earthly friends, are but shadows; but God is the substance. These are but scattered beams, but God is the sun. These are but streams, but God is the ocean.
