All of what is seen, whether in the flesh or in visions, is manifest, but only manifest and not the Spirit, but in the spirit. Christ explains the nature of all that is spirit, and John explains that (at that time) they did "not yet know what we shall be", but that when we see Christ, we will see Him "as His is", "for we will be like Him." But what you have described is seeing as the world sees, which they particularly say is not at all how things work in the spirit.
As I recall, the last book John wrote was revelation. It's called revelation for a reason, its because the time for allegories and parables are over with. I'm only describing the "spirit" as John saw it, not as "the world" would see it. When John describes the presence of blood in heaven, then I have no reason to conclude otherwise, or try and explain it away like most Christians do to make it seem so mystical. But no, of course you know better than John, the person who witnessed it, so I guess I'm supposed to take your word for it over his.
That is an assumption. On the contrary, the word of God tells us that the body returns to the earth, and the spirit to God who gave it. In Christ's example He did not commit His flesh to the Father, but His spirit only. Therefore, the transfiguration, does not result in a glorified flesh body, but in a spirit body...which we already have if we are in Christ and He in us. But that new spiritual body is not our old man of flesh, but a [completely] new and different creation within, that at this time cannot be seen (just as John made clear).
"the word of God tells us that the body returns to the earth, and the spirit to God who gave it"
I believe you are quoting Ecclesiastes here, which is not at all a revelation of the nature of heaven, but of the philosophy of Solomon. It makes this very clear at the very beginning of the book, that the book is all about life "under the sun". Nothing in it is meant to be taken as Christian doctrine concerning the affairs in heaven. Another scripture people love to quote as proof that the spirit returns to God by default without a body is from Paul stating that "to be absent from the body is to be present from the lord". Here is the whole stricture to get some context folks.
(2 Corinthians 5:1-8) "For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens. {2} For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven: {3} If so be that being clothed we shall not be found naked. {4} For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life. {5} Now he that hath wrought us for the selfsame thing is God, who also hath given unto us the earnest of the Spirit. {6} Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord: {7} (For we walk by faith, not by sight {8} We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord."
At no point does he actually state that the spirit exist without a body. What he actually says is that he does not want to be unclothed (without a body) from this current "tabernacle" which is of the earth, but further clothed (with a body) with the "building of God" that awaits us in heaven, you know, that "glorified body" he later spoke of. This is a far cry from any notions of a disembodied spirit. In context, it never supports the assumption that we will be in Gods presence without a body, nor does it ever state this to be so anywhere else. In fact, this is further illustrated when Peter spoke of the body of David below, plainly stating that he has not ascended into heaven. If David isn't in heaven, then there sure as hell isn't any reason to believe that you will either, unless you believe yourself to be that special to assume that God would specifically want you there.
(Acts 2:29-36) "Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. {30} Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; {31} He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. {32} This Jesus hath God raised up, whereof we all are witnesses. {33} Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. {34} For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand, {35} Until I make thy foes thy footstool. {36} Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ."
No, it does not say "incorruptible [flesh]" at all, but only "incorruptible." You cannot [add] the flesh to what is written (even the word is spirit). Certainly, there is no "promise" of "incorruptible flesh."
Again, it is a grave assumption to assume that Jesus ascended into heaven in the flesh, when the scriptures do not say that.
It is a far bigger assumption to claim that the same body Jesus rose from the dead with is not the same body he is presently in heaven with. To even begin to make such a claim, you have to show us where it actually states that a change of state actually occurs. In fact, don't even bother, because I have requested such a verse time and again to no avail. No change of state was required for Jesus Christ to ascend into heaven because his body was already made incorruptible. It makes it very clear that his body never saw any corruption to begin with in fact because he knew no sin, and this is what is always overlooked.
Since John said that they did "not yet know what we shall be" after witnessing Jesus' ascension - he could not have seen Him enter in the flesh - and unlike us just now discussing or reading of it...he was there. Therefore, we have no choice but to believe the other passages that say that flesh and blood cannot and do not enter the kingdom of God. If we go against this, we go against John's witness.
He knows now, its called Revelation. Its not a mystery, its been revealed. You can either believe the word of God, or just make up your own gibberish. It makes no difference to me.
