You obviously have not studied the Isaiah 25:5-9 Scripture where Apostle Paul was pulling from with the idea of 'death swallowed up in victory' (1 Corinthians 15:54). In that Isaiah Scripture God is hinting at the 'change' at the 'twinkling of an eye' that Paul taught as being for ALL NATIONS AND PEOPLES.
Well 'obviously' neither have you studied Isaiah 25, because it is talking of God ruling from Mount Zion, on the earth, ruling over humans. There is no mention of people being changed into spirit beings.
Paul's letter to the Corinthians was addressed to Christians only, not to everyone in the world. In chapter 15 he addresses his "brothers" in Christ. Therefore it is only Christians who will be changed into spirit beings.
1 Corinthians 15:50 (WEB):
Now I say this, brothers, that flesh and blood can’t inherit God’s Kingdom; neither does the perishable inherit imperishable.
Romans 8 (WEB):
16) The Spirit himself testifies with our spirit that we are children of God;
17) and if children, then heirs; heirs of God, and joint heirs with Christ; if indeed we suffer with him, that we may also be glorified with him.
Only Christians, as adopted sons of God, will inherit God's kingdom, and be joint heirs with Jesus, our head. This is something new which Paul reveals - 1 Corinthians 15:51 (WEB):
Behold, I tell you a mystery. We will not all sleep, but we will all be changed,
which applies to Christians only, who are changed to receive the divine nature. It applies only to those whom God calls to become members of the body of Christ:
2 Peter 1 (WEB):
3) seeing that his divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us by his own glory and virtue;
4) by which he has granted to us his precious and exceedingly great promises; that through these you may become partakers of the divine nature, having escaped from the corruption that is in the world by lust.
And the idea that the wicked dead aren't raised from the dead until after the Rev.20 "thousand years" is a myth based on fleshy thinking,
It's based on a misunderstanding of "The rest of the dead didn’t live until the thousand years were finished" (Revelation 20:5). It means that they didn't have eternal life until after they had lived through the 1,000 years, during which they are brought back to human perfection, and after the final testing when Satan is released to test them - only the faithful who don't side with Satan will be granted eternal life; those who fail the test will die again (second, and eternal, death). This is the "resurrection of judgement" mentioned in John 5:29 - a long period of trial ending with a judgement of worthiness for eternal life.
And NO, the 1611 KJV Bible is definitely NOT a POOR TRANSLATION. That's a stupid idea, because the later modern Bible translations aren't even based on the same Bible manuscripts as the KJV!
The poor translation I was referring to was just the translation of the Greek word
krisis which the KJV renders as 'damnation' rather than 'judgement'. Strong's describes it as:
decision (subjectively or objectively, for or against); by extension, a tribunal; by implication, justice (especially, divine law)
The Online Bible Greek Lexicon says:
1) a separating, sundering, separation
1a) a trial, contest
2) selection
3) judgment
3a) opinion or decision given concerning anything
3a1) esp. concerning justice and injustice, right or wrong
3b) sentence of condemnation, damnatory judgment, condemnation and punishment
4) the college of judges (a tribunal of seven men in the several cities of Palestine; as distinguished from the Sanhedrin, which had its seat at Jerusalem)
5) right, justice
