"Once we had no delight in God, and Christ was just a vague historical figure. What we enjoyed was food and friendships and productivity and investments and vacations and hobbies and games and reading and shopping and sex and sports and art and TV and travel...but not God. He was an idea--even a good one--and a topic for discussion; but He was not a treasure of delight.You can read Desiring God online for free here.
Then something miraculous happened. It was like the opening of the eyes of the blind during the golden dawn. First the stunned silence before the unspeakable beauty of holiness. Then the shock and terror that we had actually loved the darkness. Then the settling stillness of joy that this is the soul's end. The quest is over. We would give anything if we might be granted to live in the presence of this glory forever and ever." John Piper, Desiring God, "Conversion" p. 73 (2003 ed.)
"In the end that Face which is the delight or the terror of the universe must be turned upon each of us either with one expression or with the other, either conferring glory inexpressible or inflicting shame that can never be cured or disguised. I read in a periodical the other day that the fundamental thing is how we think of God. By God Himself, it is not! How God thinks of us is not only more important, but infinitely more important. Indeed, how we think of Him is of no importance except in so far as it is related to how He thinks of us. It is written that we shall "stand before" Him, shall appear, shall be inspected. the promise of glory is the promise, almost incredible and only possible by the work of Christ, that some of us, that any of us who really chooses, shall actually survive that examination, shall find approval, shall please God. To please God...to be a real ingredient in the divine happiness...to be loved by God, not merely pitied, but delighted in as an artist delights in his work or a father in a son--it seems impossible, a weight or burden of glory which our thoughts can hardly sustain. But it is so." C. S. Lewis, The Weight of Glory.You can read The Weight of Glory online for free here.
