The other day, I posted this:

You may deny a creator God exists. That is your prerogative. But from a Christian perspective, I think the arguments for the existence of God are far easier and much more compelling than any argument I might make for a general resurrection in isolation (notwithstanding the crossover arguments that are also very strong for the resurrection of Jesus himself). But if we feel on stronger ground defending the existence of God – and I think we should – if the premise is accepted, any claim of the impossibility of a general resurrection melts away. If you accept particularly the cosmological and the teleological arguments for God’s existence – and they are pretty strong – a general resurrection is no hurdle at all after that. And, of course, if that creator God exists, the concept of spending eternity with him is no longer very farfetched (why would he create us otherwise?) And if that’s true, then needing a body in which we will spend eternity with him makes perfect sense.

To that end, here is William Lane Craig offering those reasons:
