The Act of Faith:

I once saw a lad on the roof of a very high building, where several men were at work. He was gazing about, with apparent unconcern, when suddenly his foot slipped, and he fell. In falling he caught by a rope, and hung suspended in mid-air, where he could neither get up nor down, and where it was evident he could sustain himself but a short time. He perfectly knew his situation, and expected that in a few moments, he must drop upon the rocks below, and be dashed to pieces.
