John T. Spach, in Reader's Digest
When their son left for his freshman year at Duke University, his parents gave him a Bible, assuring him it would be a great help. Later, as he began sending them letters asking for money, they would write back telling him to read his Bible, citing chapter and verse. He would reply that he was reading the Bible&md;but he still needed money. When he came home for a semester break, his parents told him they knew he had not been reading his Bible. How? They had tucked $10 and $20 bills by the verses they had cited in their letters.
