Imagine you are hiking in the mountains and you slip off the edge of a cliff. You grab hold of a bush with your hands, but you’re now dangling over hundreds of feet below. You’re safe for the moment, but you can’t hold on for long. You must have help that is immediate, good, and adequate.
Now suppose help appears. Someone reaches down and says, “Take my hand, and I’ll pull you up“. Will you do it? The answer depends on the helper. Suppose it’s someone you deeply offended at one time. He may be strong enough to help, but will he? Or suppose it’s a ten year old Boy Scout with 20 merit badges. You know he will do everything in his power to help, but does he have enough strength? What will persuade you to trust the help offered? You must be convinced of the good will, reliability, and strength of the helper.
