Walking on Water

"There are two kinds of ice: thick and thin. You can have very little faith in thick ice and it will hold you up just fine; you can have enormous faith in thin ice and you can drown. It's not the amount of faith you can muster that matters up front. It may be tiny, like a mustard seed. But your faith must be invested in something solid."

Lynn Anderson, quoted by Lee Strobel in "The Case for Faith", page 334
