Holy Sweat, Tim Hansel, 1987, Word Books Publisher, pp. 46-47.
One day, while my son Zac and I were out in the country, climbing around in some cliffs, I heard a voice from above me yell, "Hey Dad! Catch me!" I turned around to see Zac joyfully jumping off a rock straight at me. He had jumped and then yelled "Hey Dad!" I became an instant circus act, catching him. We both fell to the ground. For a moment after I caught him I could hardly talk. When I found my voice again I gasped in exasperation: "Zac! Can you give me one good reason why you did that???"
He responded with remarkable calmness: "Sure...because you're my Dad." His whole assurance was based in the fact that his father was trustworthy. He could live life to the hilt because I could be trusted. Isn't this even more true for a Christian?
