How does your post above answer the question of what went on in the spiritual realm before God----?
1 Peter explicitly states Christ was foreknown before the foundation of the world as the perfect blemish free sacrifice and he was revealed in those last times.
1 Peter 1:20-21
For He was foreknown before the foundation of the world but has appeared in these last times for the sake of you who through Him are believers in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God.
That answers the question, "
What went on in the spiritual realm before God?"
However, I will argue dichotomies like "
spiritual" and "
earthly" or "
physical" are false. They are the assumption to be avoided. Before the heavens and the earth were created there was only God. No dichotomies of any kind. Because the heavens and the earth are created at creation - together - any dichotomy that asserts absolutely no overlap, no share domain, is the assumption needing proving.
Christ was foreknown as the perfect sacrifice. That's what went on in the spiritual realm before God.
I think it is a presupposition to assume that Christ came for any other reason than to atone for sin.
Again, scripture tells us quite explicitly we were sown corruptible/perishable and mortal. It just as explicitly states we (the saints) will be raised incorruptible/imperishable and immortal. That is the outcome.
1 Corinthians 15:42-54
So also is the resurrection of the dead. It is sown a perishable body, it is raised an imperishable body; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. If there is a natural body, there is also a spiritual body. So also, it is written, "The first man, Adam, became a living soul." The last Adam became a life-giving spirit. However, the spiritual is not first, but the natural; then the spiritual. The first man is from the earth, earthy; the second man is from heaven. As is the earthy, so also are those who are earthy; and as is the heavenly, so also are those who are heavenly. Just as we have borne the image of the earthy, we will also bear the image of the heavenly. Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable. Behold, I tell you a mystery; we will not all sleep, but we will all be changed, in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed. For this perishable must put on the imperishable, and this mortal must put on immortality. But when this perishable will have put on the imperishable, and this mortal will have put on immortality....
Notice Paul said flesh and blood cannot inherit the kingdom. Adam and Eve were flesh and blood. Even in their good, unashamed, and sinless state they were flesh and blood. According to 1 Cor. 15:50 they could not have inherited the kingdom of God. Notice also Paul says, "
sown perishable." The word here in the Greek means decay or rot or corruption; that is why I use the word "
corruptible." Otherwise "
perishable" and "
mortal" are unnecessarily redundant, and the reader misses the distinction about which Paul is writing. We might think Paul was referencing "perishable" as a consequence of being sinful but if that were the case he would have to use the word, "
perished," or "
corrupted" (past-tense). He does not use that ending. Instead he says, "
perishable," or
corruptible."
1 Corinthians 15:42-44
So also is the resurrection of the dead. It is sown a perishable body, it is raised an imperishable body; it is sown in dishonor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body.
Paul appeals to the "
sowing" of a perishable body. Who is the sower? Who did the sowing? The body of flesh and blood God "sowed" into the world was good, unashamed, and sinless but it was perishable. It was not already-perished. The body buried is sown perished, not perishable. That guy who gets tossed in the grave is twice-dead; he's died once in sin and then again died physically. He is not perishable, he is perished. Perishable AND mortal.
So there is reason to KNOW, not assume, Paul is writing about something other than the effects of sin.
Flesh and blood cannot inherit the kingdom of God and humans were made corruptible and mortal not corrupted and not immortal. All of those conditions existed prior to Genesis 3:6
The Bible unequivocally tells us that is why He came.
Yes, it does but not a single one of those verse uses the word "only".
