What does the Bible say about this question- Why do Jesus and God have two seats in heaven when they are the same God? Please answer! I have been wondering for ages! I have tried google and all sorts, but can't find the answer.
Jesus and the Father are one God, but they are two persons. Two persons deserve two seats.

To expand slightly, according to mainstream (i.e. Trinitarian) Christianity, Jesus and the Father are separate persons. In fact this passage is considered evidence that Jesus is not simply a different manifestation of God the Father. I recommend consulting a detailed explanation of the Trinity for more information.

Mike gives an excellent answer describing the imagary, by the way.
