Two countries were at war. The bigger country prayed to God, "God, our Lord! That country may be small but they are very vicious! They refuse to obey us or offer tributes to us every year. Would You please help us hit their capital and kill them all tomorrow!" God didn't say anything. The next day, the bigger country came back: "Why? Didn't we ask You in our prayers to help us strike their capital and kill them all? Why did You send our missiles into the sea. What do You mean by that?"
God replied, "Well, I am sorry! But your rival country also prayed to me for exactly the same thing!"
