"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.
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 might be granted to live in the presence of this glory forever and ever.
And then, faith--the confidence that Christ has made a way for me, a sinner, to live in His glorious fellowship forever, the confidence that if I come to God through Christ, He will give me the desire of my heart to share His holiness and behold His glory.
But before the confidence comes the craving. Before the decision comes the delight. Before the trust comes the discovery of Treasure."
I looked for a great, up-lifting, feel-good type song to insert here, but what I found was this video of John Piper instead. It is the foundation of the entire book. Maybe a hard pill to swallow...but don't judge the book on a 5 min clip of a sermon. Instead, let it whet your appetite to hear more.
