A fast post

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 the ill that Satan can do, when God
describes what keeps us from the banquet table of his love, it is
a piece 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 the simple pleasures of earth. For when these replace an
appetite for God himself, the idolatry is scarcely recognizable,
and almost incurable.

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. 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.”
