In Christianity, heaven is traditionally the location of the throne of God and the angels of God, and in most forms of Christianity it is the abode of the righteous dead in the afterlife. In some Christian denominations it is understood as a temporary stage before the resurrection of the dead and the saints' return to the New Earth. In the Christian Bible, concepts about Christian eschatology, the future "kingdom of heaven", and the resurrection of the dead are found, particularly in the book of Revelation and in 1 Corinthians 15.
