You don't have to convince Muslims of God's existence or importance.

This is the secret of life: the self lives only by dying, finds its identity (and its happiness) only by self-forgetfulness, self-giving, self-sacrifice, and agape love.

Your heart is like an infinitely large hole, and only God is big enough to fill it.

A man walking through a wall is a miracle. A man both walking and not walking through a wall at the same time and in the same respect is a contradiction. God can perform miracles but not contradictions - not because his power is limited, but because contradictions are meaningless.

The big, blazing truth about man is that he has a heaven-sized hole in his heart, and nothing else can fill it. We pass our lives trying to fill the Grand Canyon with marbles. As Augustine said: Thou hast made us for Thyself, and our hearts are restless until they rest in Thee.

But how can we love someone if we don't like him? Easy-we do it to ourselves all the time. We don't always have tender, comfortable feelings about ourselves; sometimes we feel foolish, stupid, asinine, or wicked. But we always love ourselves: we always seek our own good. Indeed, we feel dislike toward ourselves, we berate ourselves, precisely because we love ourselves; because we care about our good, we are impatient with our bad.

When a maniac is at the door, feuding brothers reconcile.
