Everyone who has this hope set on him purifies himself, even as he is pure.
It doesn't yet appear what we are gonna be. Paul said, "Some of you will ask, 'How are the dead raised? With what body will they come?'" ( 1 Corinthians 15:35 ) And he doesn't really seek to tell us too much about the body, only in the fact that it's going to be vastly superior to the body that we have. We're planted in corruption; we're going to be raised in incorruption. We're planted in weakness; we're going to be raised in power. We are sown in dishonor; we're going to be raised in glory. We're planted as a natural body; we're going to be raised in a spiritual body. There is a natural body; there is a spiritual body. As we are born in the image of the earth, so shall we bear the image of the heavens. When you put a seed into the ground it dies before it comes forth into new life, and the body that comes out of the ground isn't the body that you planted. All you planted was a bare grain and God gives it a body that pleases Him, so is the resurrection of the dead.
