I promise

Two men were adrift in a deep sea in an open boat and a sudden problem occurred. The situation looked bleak for them for survival. Finally one of them, frightened to bits, began to pray, “O Lord, I’ve broken most of Thy commandments. I’ve been a hard drinker all these days, but if you spare my life, from now on  I’ll promise Thee never again……”  “Wait a minute, Jack,” said his friend. “Don’t continue, I think I see a rescue sail.”
