What is the Greek word for "positionally"? There is none. But there is an equivalent term: "spiritually". We are spiritually seated in the heavenlies.
I am not sure, but I suspect that much is made today of positional truth because of doctrinal discomfort with the ramifications of using the word "spiritual". It has become a dirty word for some: spiritual -> spiritualize -> allegorize -> disbelief.
And yet the main emphasis in the Bible is on spiritual reality.
The kingdom is spiritual, not physical.
The resurrection of believers (Note: I am writing of believers) is spiritual, not physical. This makes it even more real than if it was merely physical. When Christ said:
"I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die." (John 11:25-26)
He was emphasizing our spiritual nature, and the spiritual nature of our new life in Him. In a very real sense we will never die. We will only sleep. The disciples misunderstood this very point in this chapter.
When it says we will be like Him it does not mean in all particulars. The passage itself, that you allude to here, provides the answer.
Your memory is correct. I say it because the Bible says it. 1 Cor. 15:50
"Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption."
You believe this too, right?
Yes.
OK then I am spiritually seated in the heavens with Christ.
However I am more than spiritual, I have a body.
My spirit at the moment is seated in the heavenlies but my resurrected body some day also as well.
But because of what you say, I have come to the realization that you in all probablity don't believe that there is to be a bodily (flesh and bone) resurrection such as Christ experienced for those who believe on Him.
Perhaps I am wrong, but... (just in case)
Luke 24
37 But they were terrified and affrighted, and supposed that they had seen a spirit.
38 And he said unto them, Why are ye troubled? and why do thoughts arise in your hearts?
39 Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have.
40 And when he had thus spoken, he shewed them his hands and his feet.
41 And while they yet believed not for joy, and wondered, he said unto them, Have ye here any meat?
42 And they gave him a piece of a broiled fish, and of an honeycomb.
43 And he took it, and did eat before them.
BTW, Luke under inspiration also wrote the book of Acts in which he gives the account of Jesus in this flesh and bone body going up through the atmosphere to heaven with a promise of a return in "like manner".
Acts 1
6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
9 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
10 And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel;
11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
This same Jesus - not Titus.
Will come from heaven - not Rome.
So,
this same Jesus of flesh and bone (not flesh and blood but flesh and bone made alive by the Spirit and not oxygenated blood) went on up through the atmosphere into heaven awaiting the "times of the Gentiles to be fullfilled" and then shall return in this same flesh and bone body (to the same place BTW, the Mount of Olives).
Back to the resurrection:
This same Jesus of flesh and bone whom John, (one of the apostles who handled Him when He appeared to them in the Luke 24 account) says the following;
1 John 1:1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
ALSO says:
1 John 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
And Paul:
Romans 6:5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
1 Corinthians 15
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
I therefore expect to have a glorified resurrected flesh and bone body just as He has while I await His return in His glorified resurrected flesh and bone body.
We shall be more than just spirit beings, we shall be like Him...
39 Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have.
