God answers the prayers of those who obey Him: some promises are conditioned on specific obedience, while others are not.

The Old Testament:

Law: The Moral Law shows God made the rules; and that every man has broken them--except Jesus.

History: God showed how every system without Him was destined to fail. In Israel, He foreshadowed Jesus as Prophet, Priest and King.

Poetry: The longing of the whole world for Jesus.

Prophecy: Hundreds of 100% accurate predictions of Jesus' first and second comings.

Atheists have an unprovable faith in God's non-existence.

They have absolutely no basis for truth or morality.

They are without God and Christ.

They are going to The Place where God's goodness is not felt.

Jews reject the Savior clearly prophesied in their own (and our) Scripture: Isaiah 53.

Those who reject Jesus are under the wrath of God and are headed for Hell.

Islam says it reveres the Bible.

But the Koran flagrantly and deeply and specifically contradicts the Bible.

The Koran instructs its faithful to kill Christians (and Jews.)

I would say that's quite a contradiction.

Those who reject Jesus are going to Hell.
