No one ever talks about what Heaven will be like before the resurrection of our bodies. If we will be just spirits without a physical body until it's resurrected, how will we be able to, for example, eat in the current Heaven? I don't think we can do what we can now without a body, so we will have to wait until then to enjoy a better existence in the New Heaven which will come to Earth as the New Jerusalem? What will we be able to do in the meantime after death? And why must both heavens be so different from what we now know in this life except for sin? I've heard of some things that people enjoy now won't likely be there. Sin I can understand won't be there, of course. Yet why would God make anything good here to just discard or even replace it after this life?
