“During the war a man lay dying in the trenches. A friend leaned over him and said, ‘Is there anything I can do for you?’

He replied, ‘No I am dying.’

‘Is there anyone I can send a message to for you?’

‘Yes, you can send a message to this man at this address. Tell him that in my last minutes what he taught me as a child is helping me to die.’

The man was his old Sunday School Teacher. When the message got to him, he said, ‘God forgive me. I gave up Sunday School teaching years ago because I thought I was getting nowhere. I thought it was no use.'”
