1 Cor. 15:42-46
42 So also is the resurrection of the dead. It is
sown in corruption; it is raised in incorruption:
43 It is
sown in dishonour; 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.
45 And
so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
Most scriptures you referenced are taken out of context and are based on your own judgment of mankind - you use those scriptures to support you, not what they truly mean.
It would take too much time to correct all of what you have said, so I will only address this part!
Adam was in a natural body - that’s true. But, his body was not a corrupted body?
1 Corinthians 15:44 KJV
It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
Before the fall, Adam had not undergone the change that would have happened if he had eaten from the Tree of Life. The Tree of life would have caused the change from a natural body to a spiritual body. But sin came in and the process from natural to spiritual was stopped. The tree of life would have changed Adam to a spiritual body that would live forever- that’s why, after Adam sinned, God had to put them out of the garden and block the way of the Tree of Life.
Genesis 3:22-24 KJV
22 “And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:”
23 “Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.”
24 “So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.”
So, now how would God fulfill His original plan for man to be a spiritual being like Himself? Man at this point of the fall had to be redeemed.
You must understand that before the fall, man did not have to be redeemed from anything. Redemption came because of sin.
Adam and all men that came after Adam was not supposed to stay as men/natural, but was supposed to be spiritual and live forever. The result of this sin or fall caused God to withdraw His Spirit from man. Genesis 6:3 KJV, “And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.”
So now, man needs a redeemer. It’s the spiritual aspect of man that’s important- so how will it be accomplished now if the Tree of Life was blocked?
1 Corinthians 15:45 KJV
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
So it is by Jesus Christ that man has been redeemed and made children of God by the Spirit- the Holy Spirit.
Redeemed from what? A fallen state in Adam.
So, if Adam was already corrupt, as you are implying, then what state did he fall from?
