The following quote from this book was very convicting; it's so easy to be carried away by all the things in this world - the 'things' that we have, the 'things' that we 'need', things that we just can't live without, be it a person, possession, dream, ambition, etc.
"The greatest enemy of hunger for God is not poison but apple pie. It is not the banquet of the wicked that dulls our appetite for heaven, but endless nibbling at the table of the world. It is not the X-rated video, but the prime-time dribble of triviality we drink in every night. For all theill that Satan can do, when God describes what keeps us from the banquet table of his love, it is a pice of land, a yoke of oxen, and a wife (Luke 14:18-20). The greatest adversary of love to God is not his enemies but his gifts. And the most deadly appetites are not for the poison of evil, but for thesimple pleasures of eath. for when these replace an appetite for God himself, the idolatry is scarcely recognizable, and almost incurable....
..."the pleasures of this life" and "the desires for other things" (Luke 8:14, Mark 4:19) -- these are not evil in themselves. These are not vices. These are gifts of God. They are your basic meat and potatoes and coffe and gardening and reading and decorating and traveling and investing and TV-watching and Internet-surfing and shopping and exercising and collecting and talking. And all of them can become deadly subsitutes for God."
"[Chrisian fasting] keeps the preferring facutly on alert and sharp. It does not let the issue rest. It forces us to ask repeatedly: do I really hunger for God? Do I miss him? Do I long for Him? Or have I begun to be content with his gifts?"
And there is none upon earth that I desire besides You.
My flesh and my heart fail;
But God is the strength of my heart and my portion forever.
Psalm 73: 25-26
