In death body and soul are separated. The body decays, while the soul goes to meet God and waits to be reunited with its risen body ont he Last Day. [992-1004, 1016-1018]
How the resurrection will take place is a mystery. An image can help us to accept it: When we look at a tulip bulb we cannot tell into what a marvelously beautiful flower it will develop in the dark earth. Similarly, we know nothing about the future appearance of our new body. Paul is nevertheless certain: “It is sown in dishonor, it is raised in glory” (1 Cor 15:43a)
