Enoch and Elijah are in heaven now, having been raptured (taken up to heaven) before their physical death, so that they will return at the end of the Tribulation to preach the Good News to the dying world, the pair of saints to be killed for their preaching then resurrected three days later for all to see. So they with Abraham (see Luke 16: 22-31) are proof that the Old Testament saints are in heaven, their bodies to be resurrected immediately before the resurrection (rapture) of the saints living at that time, taken up to heaven to join the Old Testament saints who looked forward to the Messiah (Jesus Christ), such as Rahab the Canaanite prostitute who repented in faith given by Elohim.
