Have you not read the letter tot he Corinthians that you quoted from? we shall ALL be changed, in the twinkling of an eye, to incorruptible from corruptible, so the body we are transformed into will not be corruptible flesh, but it will have physicality. I could explain it to you in more technical detail but something tells me you don’t want to have anything impinge upon your comfy level of understanding.

It will be a spiritual body, as Yeshua explained very aptly to Nicodemus in John 3:8
It will be able to move through the physical universe invisibly as does the wind.
John 3:
[5] Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
[6] That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
[7] Marvel not that I said unto thee, Ye must be born again.
[8] The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth:
so is every one that is born of the Spirit.
So flesh man will be in the Kingdom of God?
