This does not follow. The payment for sins has nothing to do with salvation/justified. In other words, sins are not the basis of eternal condemnation.
Romans 6:23
(23) For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
We cannot be restored to life (eternal life) unless somebody pays the penalty of death for us. Jesus did that, by willingly dying for us. God was justified in restoring Jesus to life again because Jesus had not sinned; our sins were placed on him, but Jesus had not personally sinned. After Jesus had paid the penalty for everyone's sins, God is justified in restoring everyone to life again.
1 Corinthians 15:3
(3) For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures,
Romans 5:8-10
(8) But God commends his own love toward us, in that while we were yet sinners, Christ died for us.
(9) Much more then, being now justified by his blood, we will be saved from God’s wrath through him.
(10) For if, while we were enemies, we were reconciled to God through the death of his Son, much more, being reconciled, we will be saved by his life.
Titus 2:13-14
(13) looking for the blessed hope and appearing of the glory of our great God and Savior, Jesus Christ;
(14) who gave himself for us, that he might redeem us from all iniquity, and purify for himself a people for his own possession, zealous for good works.
Galatians 3:13
(13) Christ redeemed us from the curse of the law, having become a curse for us. For it is written, “Cursed is everyone who hangs on a tree,”
1 Peter 1:18-19
(18) knowing that you were redeemed, not with corruptible things, with silver or gold, from the useless way of life handed down from your fathers,
(19) but with precious blood, as of a lamb without blemish or spot, the blood of Christ;
Only believers are resurrected until the final judgment called the Great White Throne judgment and then unbelievers are resurrected, judged, and sent to the Lake of Fire.
A common misunderstanding. It does not make sense that Christ would set up a righteous kingdom and rule in righteousness and with a rod of iron for 1,000 years, and then quickly resurrect the majority of mankind that has ever lived only to immediately declare them all unworthy of life and to kill them all again. How would they benefit from Christ's reign? Who is Christ reigning over for 1,000 years? Christians are resurrected before the start of the 1,000 years reign (for they will be reigning with Jesus - Revelation 20:4), then everyone else that has ever died will be resurrected at the beginning of the 1,000 years reign. God has allowed 1,000 years for their learning and restitution to become perfect humans - Acts 3:20-23 (WEB):
(20) and that he may send Christ Jesus, who was ordained for you before,
(21) whom heaven must receive until the times of restoration of all things, which God spoke long ago by the mouth of his holy prophets.
(22) For Moses indeed said to the fathers, ‘The Lord God will raise up a prophet for you from among your brothers, like me. You shall listen to him in all things whatever he says to you.
(23) It will be that every soul that will not listen to that prophet will be utterly destroyed from among the people.’
Only at the end of the 1,000 years will they be tried and judged whether or not they are worthy of eternal life. Only then will they live again (live eternally), hence the comment, Revelation 20:5 (WEB):
(5) The rest of the dead didn’t live until the thousand years were finished. This is the first resurrection.
[Scholars agree that the first part of verse 5 is an interpolation that probably crept into the text by accident in the fifth century; at first a marginal comment made by a reader expressive of his thought, later copied into the text by transcribers who failed to distinguish between the text and the comment.]
People are saved during the Millennium by accepting Christ.
Indeed. Just as Christians are saved during this Gospel Age. The only difference is that those that are called and accepted during the Gospel Age have a better resurrection and become sons of God (John 1:12 - "But as many as received him, to them gave he power [
authority, right, privilege] to become the sons of God, even to them that believe on his name"), resurrected as a new creation of spiritual beings, just as Jesus now is (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"). But after the resurrection and rapture of the Church the opportunity to become members of the body of Christ and joint heirs with him will have come to an end. All non-Christians will have the opportunity of eternal life as humans, living on the Earth.
Revelation 11:15 (WEB):
(15) The seventh angel sounded, and great voices in heaven followed, saying, “The kingdom of the world has become the Kingdom of our Lord, and of his Christ. He will reign forever and ever!”
The rest of what you posted I can't follow. Sorry.
There's no need to apologise. We're all trying to learn the true understanding of the Scriptures. It takes time (a lifetime!).
