This sort of does Enoch and Elijah in does it not.'The flesh returns to the dust and the elements of the earth which are destroyed by fervent heat and with fire, and the spirit returns to God who gave it. Nothing else is biblical. There is no such thing as a "glorified flesh body."
I do not completely understand the events to come, but @Earburner is quiet right about a number of things, It seems that all the argument is over flesh and blood, which I do not have understanding. This I do know . we who are born of the spirit, received His Spirit, have being to the cross, have now as HE did, passed from death to life, for us there is no more judgement, for we now walk that narrow path that leads to life. When Christ comes, the scriptures say, in the twinkling of an eye we will all be changed. We who are pregnant with the seed of God, and who have nourished this seed by His word,
Joh 6:32 Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven.
Joh 6:33 For the bread of God is he which cometh down from heaven, and giveth life unto the world.
Joh 6:34 Then said they unto him, Lord, evermore give us this bread.
Joh 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
What we change into I do not pretend to understand but Christ nor Elijah nor Enoch left a body behind. Until l I get further understanding im not going to guess. Its one I dont think on this one often.
