"WE SHALL ALL BE CHANGED".             
HOW, AND WHEN?            

"Look! I tell you a sacred secret: We shall not all fall asleep in death, but we shall all be changed, in a moment, in the twinkling of an eye, during the last trumpet. For the trumpet will sound, and the dead will be raised up incorruptible, and we shall be changed. For this which is corruptible must put on incorruption, and this which is mortal must put on immortality."  (1 Cor 15:51-53).

The "change" described in verse 51 is the promised gift to all faithful anointed sons of God who die in union with Christ. Sadly, on this point the Scriptures are misunderstood by many. This "changed" existence is the gift of future incorruptible heavenly life from Almighty God, His promised reward of immortality to all the holy ones. (Rev 11:18). And this is how that promise shall be fulfilled: "Those who are dead in union with Christ will rise first. Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air".  (1 Thess 4:16,17).

According to the scripture, this gift of "change" will occur during the period of the "last trumpet". This "last trumpet" is the seventh "trumpet" and third "woe" that follows the "sounding" of spiritual events leading to it. (Rev 11:15.  Pages 2/11/85A & 2/11/85B) Anointed sons of God still alive on earth receive Spirit notification in their spirits of this promised gift of "change". (Eph 1:13,14).  But although their spirits are thereby invested with future immortality, they continue to live on in corruptible bodies of flesh inherited from the first Adam until their spiritual work on earth is completed and Almighty God disposes of this corruptible "tent". (2 Cor 5:1-5). The earthly body or "tent" of each of the holy ones is for the creating and sealing of their spirits while residing in it     for God to inhabit by Spirit in connection with His progressive Will regarding all mankind.

So the meaning of "…we shall all be changed, in a moment, in the twinkling of an eye, during the last trumpet. For the trumpet will sound, and the dead will be raised up incorruptible, and we shall be changed" can now be understood. Faithful anointed ones who have died in union with Christ will only be permitted to put on incorruptible new spirit bodies when those of their anointed brothers on earth are ready to be resurrected  "together with them", "caught away in clouds to meet the Lord in the air".  (1 Thess 4:17.  1 Cor 15:44).

THE WAYS OF GOD FOR SPIRIT IMMORTALITY.
In Job 33:12-30 the ways by which men may gain spirit immortality from God are described:

After this exhortation from Jehovah, immortality becomes the glorious conclusion of their faith. For it is written: "Yet if an angel, one of thousands, stands by him, a mediator between him and God, to expound what he has done right and to secure mortal man his due; if he speaks in the man's favour and says, 'Reprieve him, let him not go down to the pit, I have the price of his release'", then the spirit of that man is free to be invested with future incorruptible immortal heavenly life.  (Job 33:23,24 NEB).

As "flesh and blood cannot inherit God's Kingdom, neither does corruption inherit incorruption", one may wonder how, at the "last trumpet", those still in corruptible flesh could inherit the heavenly Kingdom of God.  (1 Cor 15:50). In order for a faithful anointed son of God on earth to be "changed, in a moment, in the twinkling of an eye" and be instantly resurrected to immortal and incorruptible heavenly life, his perishable spirit must already have been clothed with the imperishable before the "last trumpet". As the heavenly Kingdom of God is one of immortal spirit life, it is the spirit of an anointed son of God that is "changed", even though for a while his spirit may remain within a corrupt physical body awaiting release to a heavenly resurrection.  (Please read 1 Cor 15:51  57 NEB).
