So you actually think that jesus is human of flesh and blood, which would mean he would eat, sleep, and poop, in heaven. He is surrounded by his spirit father, and spirit angels, yet he is human? Who cuts his hair? Does he wear clothes? What kind of clothes? How about shoes.....does he wear them too.? If so....why would he need shoe's in a spirit realm?
The scriptures show that Jesus is a human man with a glorious body of flesh. As far a bodily functions and needs in heaven go the scriptures are silent. Perhaps the body is sustained physically, but it is probably sustained by the Spirit.
