I believe when we are immortalized, we won't need to upkeep our bodies. Like feed, bathe & dress them. We will be able, but we won't need to. I believe we will be more like spirits but somehow producing bodies to eat & socialize. Scripture says God is a Spirit (John 4:24). It also says when He appears we will be like Him (1 John 3:2).
Jesus also suggests we and He will eat in the Kingdom: Matt. 26:29 "But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father's kingdom."
It all fits together somehow, but through glass darkly--right now (1 Cor. 13:12).
What do you think about all that?
