What do we know about Heaven? Is it more than an eternal song service telling God how wonderful he is? Why do we need physical bodies in the next life? Will we be doing anything useful? Useful to humans? To God? Was Adam's "work" in the Garden "make work?" Who did it after Adam was kicked out? Do people in Heaven ever think about the real world they left behind and the people in it? Out of sight, out of mind? We have a "mind wipe?"
