Quote about Prayer by C.S. Lewis: "I pray because I can't help myself. I pray because I'm helpless. I pray because the need flows out of me all the time, waking and sleeping. It does not change God, it changes me.
Fully trusting God will enable you to take that leap of faith. God knows our heart and the true desires of it. What a testimony it has been since I stepped out taking a huge leap of faith - trusting that God would in fact lead the way.
