If God should turn away from himself as the Source of infinite joy, he would cease to be God. He would deny the infinite worth of his own glory. He would imply that there is something more valuable outside himself. He would commit idolatry... Where will we find a Rock of integrity in the universe when the heart of God has ceased to value supremely the supremely valuable?
Desiring God: Meditations of a Christian Hedonist (Multnomah, 1986, ISBN 1590521196.
We need God in ways we do not know. Don't limit your experience of God to what you can think to ask. Ask for the unknown joy.
If you don’t feel strong desires for the manifestation of the glory of God, it is not because you have drunk deeply and are satisfied. It is because you have nibbled so long at the table of the world. Your soul is stuffed with small things, and there is no room for the great.9 God did not create you for this. There is an appetite for God. And it can be awakened. I invite you to turn from the dulling effects of food and the dangers of idolatry, and to say with some simple fast: “This much, O God, I want you.”
