"What kind of body will we have in heaven (assuming we get there!)?"

1 Corinthians 15:35-44
'But someone may ask, "How are the dead raised? With what kind of body will they come?" How foolish! What you sow does not come to life unless it dies. When you sow, you do not plant the body that will be, but just a seed, perhaps of wheat or of something else. But God gives it a body as he has determined, and to each kind of seed he gives its own body. All flesh is not the same: Men have one kind of flesh, animals another, birds another and fish another. (ie they did not evolve from each other but were created by God according to their own kind. Refer Genesis 1:21) There are also heavenly bodies and there are earthly bodies; but the splendour of the heavenly bodies is one kind and the splendour of the earthly bodies is another. The sun has one kind of splendour, the moon another and the stars another; and star differs from star in splendour.

So it will be with the resurrection of the dead. The body that is sown is perishable, it is raised imperishable; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body.
