Praying for world peace is a sucker's bet. Try praying for peace in your own heart. That's what the great Jihad is in the Muslim sense. "Muslim" is an Arabic word that means "one who submits to the will of God".
I am not a Muslim, or a Christian, or a Jew, but I think maybe the Muslims are the ones who are devoting the most energy trying to do the right thing every day on an individual basis. For one thing, I think most of them actually believe as opposed to most Christians and Jews. Gotta respect that.
