DeighAnn,
Part 2 of your question:
1 Corinthians 15:49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
1 Corinthians 15:50 Now this I say, brethren,
that flesh and blood cannot inherit the kingdom of God;
(NO PART OF OUR EARTH BODY WILL GO TO HEAVEN) neither doth corruption inherit incorruption
(OUR FLESH BODIES ARE CORRUPT BY PAUL'S DEFINITION. THEREFORE OUR FLESH BODIES CANNOT BE PART OF OUR SPIRITUAL INCORRUPT BODIES).
1 Corinthians 15:51 Behold, I shew you a mystery; We shall not all sleep
(SLEEP = WAITING IN HADES), but we shall all be changed (DON'T HAVE TO WAIT IN HADES ANYMORE),
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 (FREED FROM HADES, RESURRECTED OUT OF HADES AND REJOINED WITH GOD IN HEAVEN), and we shall be changed.
1 Corinthians 15:53 For this corruptible must put on incorruption, and this mortal must put on immortality.
1 Corinthians 15:54 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
(SEPARATION FROM GOD) is swallowed up in victory.
1 Corinthians 15:55 O death, where is thy sting? O grave, where is thy victory?
As I mentioned before, you have to look at the whole passage. Please don't just cherry pick the portion, which on the surface, might support your view. Paul makes clear - You cannot be made alive (spiritual body) unless you first die physically.
35 But someone will say, “How are the dead raised up? And with what body do they come?”
36 Foolish one, what you sow is not made alive unless it dies. (This totally contradicts what you think Paul is saying later about changing. More on that later. Paul is clear WE MUST ALL DIE BEFORE WE CAN GO TO HEAVEN).
37 And what you sow, you do not sow that body that shall be (He's saying our current body has nothing to do with our future spiritual body, its mere grain), but mere grain—perhaps wheat or some other grain.
38 But God gives it a body (after death) as He pleases, and to each seed its own body.
39 All flesh is not the same flesh, but there is one kind of flesh of men, another flesh of animals, another of fish, and another of birds.
40 There are also celestial bodies and terrestrial bodies; but the glory of the celestial is one, and the glory of the terrestrial is another. 41 There is one glory of the sun, another glory of the moon, and another glory of the stars; for one star differs from another star in glory. (Our brightness in Heaven is our reward. Just as Christ was glorified upon His re-entry to Heaven, so shall we be. Our works on earth determine our brightness or glory in heaven.)
42 So also is the resurrection of the dead. The body is sown in corruption, it is raised in incorruption.
43 It is sown in dishonor, it is raised in glory. It is sown in weakness, it is raised in power.
44 It is sown a natural body, it is raised a spiritual body. There is a natural body, and there is a spiritual body. (these are separate bodies. The natural is corrupt and cannot be a part of the spiritual body).
45 And so it is written, “The first man Adam became a living being.” The last Adam (CHRIST) became a life-giving spirit.
46 However, the spiritual is not first, but the natural, and afterward the spiritual.
47 The first man was of the earth, made of dust; the second Man is the Lord from heaven.
48 As was the man of dust, so also are those who are made of dust (physical, corrupt, of this earth); and as is the heavenly Man, so also are those who are heavenly.
49 And as we have borne the image of the man of dust (Adam & Eve, human, physical), we shall also (after death) bear the image of the heavenly Man (Christ, God, Spiritual).
Since the first resurrection of the just occurred in 66-68 AD, there are no more resurrections for believers. We don't need to be resurrected when we die. The resurrection was
NOT a coming back to this planet in any form. The resurrection was the escape from Hades and going to Heaven. It was a one-time event for believers. Since then when a believer dies, he/she immediately goes to heaven. Our spirit steps out of our dead flesh body in the spiritual realm and enters heaven and is glorified based on our works. The "change" Paul mentions is not a change whereby our flesh body coverts into a spiritual body. This is impossible because Paul already told us
"what we sow is not made alive (spiritual) unless it dies." Therefore the change as I see it, is our spiritual self was reprogrammed or coded (as I call it) to go to Heaven instead of Hades.
Heb 9:27 And as it is appointed for men to die once, but after this the judgment,
Really thing about this. I hope it helps as you continue seeking the truth?
