 The resurrection of the body is a guarantee from God. And we can see evidences of this as we look around the world. And those who deny this reality are fools. Verse 35 makes it very clear that those who were questioning and doubting the resurrection were doing so on the basis of some questions that they couldn't figure out. But someone will say, how are the dead raised? They were toying with questions of philosophy. They apparently couldn't figure out how the resurrection would work properly.
