1 peter 3:18 'for christ died once for all time for sins, a righteous person for unrighteous ones, in order to lead you to God. He was put to death in the flesh but made alive in the spirit.
Argue with the apostle Peter.
No need to argue with them, just to try to understand them.
The question is when was he made alive in the spirit? After death or while living as a human before his death?
The phrase, "made alive", does not have to mean, "resurrection". Compare: Ephesians 2:1, 5; Colossians 2:13
And now realize what Jesus did for us by pondering that comparison above to Philippians 2:5-11
The point of those words, "made alive", you are wasting on material thinking. Jesus had surrendered all his glory which he had beside God before the world began, and he did so to become like us bearing our guilt of sin upon himself so that he could conquer sin for us. That means Jesus allowed himself to visit our place of spiritual captivity so that upon walking victoriously up and out of that place of captivity he could carry many out of that bondage along with himself.
Of course you will try to argue that as you are so sure that you understand what you do not. Stop and think. Paul said being bound under that Old Law constituted that place of captivity. And you know this, as follows: Galatians 4:4-5 "But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law, To redeem them that were under the law, that we might receive the adoption of sons."
Jesus was made alive first, before any others who came up and out from under that Old Law. And so it is completely true that though he was put to death in the flesh for having done so, he had been made alive in the spirit, thus showing us that he could be faithful clear to the end in accord with his own words, "fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell." Matthew 10:28
It is going to take you a moment but if you will humbly ponder it our faithful Father will not let you go long without understanding it. Then you will see that you are attaching Peter's words to the wrong thing. Then you will understand that Peter is referring to, "the answer of a good conscience toward God", that alive spiritual state we must attain to, having risen out of our bondage along with Christ as he rose out of his willing bondage to that Old Law as a human, even though he knew it would mean his being put to death in the flesh..
The entire context of that chapter of Peter ought to begin making better sense to you now.
Even at 1 Corinthians 15:45 (And so it is written, "The first man Adam was made a living soul; the last Adam was made a quickening spirit.")
Note that is talking not about what the first or the last Adam became after death. No, but it says clearly, "The first man Adam was made a living soul".
Then it contrasts that to how the last Adam was made, not how he died: "the last Adam was made a quickening spirit."
Just as Adam was surely made a living soul long before his death, even so the last Adam was made a quickening spirit long before his death.
Where else would he get the power to resurrect?
It is the tiny things we miss seeing that we stumble over.
