How do we mean when we say physical, spiritual, resurrected bodies? Jesus walked along the road with the two men, and he walked right through a door at the house the disciples were staying, and he just appeared or vanished. So, what precisely do we mean when we say physical bodies? Will there be no work in any upkeep with our bodies or gardening the earth or gathering the crops?
As to the makeup of our new "incorruptible/spiritual" bodies, this is an area where we really don't have a lot of specific information. However:
1. We shall be recognizable, which we learn from the disciples recognizing Christ after His resurrection.
2. Not sure about Jesus walking "right through a door"... I think this is unclear.
3. Re: appearing and vanishing, I'm not sure that this pertains to us. It may be unique to the incarnate God.
4. I believe we shall be occupied with work on the New Earth, tending to it as did Adam in the Garden.
5. Re: upkeep of our bodies. Again, not much information given. But eating and drinking will be something we can do. Whether if will be necessary is likewise unclear. What is clear is that God created man with a body and a soul. The body is the 'house' for the soul and thus it is necessary.
What will happened to Heaven and how about Hell? Do heavens in Revelation mean 'the sky' because why would heaven need restoring.
The word 'heaven' is used in different ways. One of the meanings is the 'abode' of God and the angels. Of course, God is not contained in heaven like the angelic beings, for they are finite. In this regard there isn't going to be much change other than the Devil and all the other rebellious angels will be removed from it. This is part of the restoration of both heaven and earth. All that was negatively affected by the Fall will be gone and transformed into perfect harmony and purity.
Why would we need to meet Jesus in the sky when we will be staying on this 'new earth'. It seems a step could be cut out by just remaining here and having our bodies changed?
Between the second resurrection and our glorification the Great White Throne Judgment must take place where justice and mercy are finalized. This cannot be eliminated, for there the great plan of God for the universe is revealed in all its glory.
