The scripture readings for the 4th Sunday of Easter give us a hint of what heaven will be. In 1 John 3:2 we read:
Even thought John says "what we will be has not yet been made known" we are left wondering. Those of us who are advanced in years - or ministering to those contemplating death - wonder even more. C.S. Lewis' The Great Divorce gives us an imaginary picture of what it might be like. His imagination, in this as well as the Narnia, and Space Trilogy, is as close as any of us are likely to get. Lewis paints some vivid pictures, which I won't even try to summarize. What we can guess is that when we see Christ as he is, and get bodies which work as they should, we will be radically different. Maybe we will be as different as the kernel of wheat after it falls to the ground and becomes a plant.
I've occasionally quipped that when I get a body that works properly I will immediately do all of my Tae Kwon Do forms properly for the first time. I suspect that this is only a small measure of what it will be like.
We can live in hope and transmit that hope to others around us. In the end, that is all we need to do.
