From Daring to Live on the Edge by Loren Cunningham:

God tells you to go out on a limb. Once you get out there, you hear a sound–rrh! rrh! rrh! You turn around, and there’s the devil with a chainsaw, cutting off your limb. Bible faith is stepping on the end of that limb and watching Satan continue to saw until the whole tree falls over with him in it and you stay aloft on your limb! That’s faith. It’s not faith in the tree or faith in the limb. It’s faith in the Word of God and faith in the One who stands behind His word.
