This article tries to give a theological explanation of the eschatological hope of bodily resurrection in the Judeo-Christian tradition; it argues that this hope is an expression of monocosmism, which is based on monotheism. The article analyses three factors of the resurrection hope: the body will be resurrected instead of being annihilated, since the body is an inner part of humanity, second, the resurrection will happen in the future as one part of a cosmological, universal event, not as an individual event that happens in this epoch of history, and third, the essence of the eschatological event is a transformation instead of an annihilation-creation, which means there is an identity between the world present and the world yet-to-come. Based on the aforesaid three points, the article concludes that the oneness of the world (monocosmism) comes from the faithfulness of God's love, which comes from God's oneness (monotheism).
