Once upon a time, there was a man who had nothing and God gave him ten apples. He gave him three apples to eat. He gave him three apples to trade for shelter from the sun and rain. He gave him three aplles to trade for clothing to wear. He gave him one apple so that he might have something to give back to God to show his gratitude for the other nine.
The man ate the three apples. He traded three for shelter from sun and rain. He traded three for clothing to wear. The man looked at the tenth apple... and it seemed bigger and juicier than the rest. So the man ate the tenth apple... and gave back to God the core!
