We are corruptible so long as we wear this flesh. We cannot be perfected in this sin-corrupted body. Yet you are saying we are perfected prior to being born sinners. Wouldn't that perfection stop us from being born a sinner?
We can be perfected while we're in this flesh. Jesus was made in the likeness of sinful flesh, yet remained perfect.
Check out:
Hebrews 10:14
14 For by one offering He has perfected for all time those who are sanctified.
Hebrews 11:39-40
39 And all these, having gained approval through their faith, did not receive what was promised, 40 because God had provided something better for us, so that apart from us they would not be made perfect.
Hebrews 12:22-24
22 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to myriads of angels, 23 to the general assembly and church of the firstborn who are enrolled in heaven, and to God, the Judge of all, and to the spirits of the righteous made perfect, 24 and to Jesus, the mediator of a new covenant, and to the sprinkled blood, which speaks better than the blood of Abel
Read the whole of Heb 8-10, where the writer contrasted the Aaronic priesthood with that of Christ, and contrasted the animal sacrifices with that of Christ.
His blood removes sin. Our inner man the spirit, is forever perfected in regeneration. But our flesh will not be perfected until the resurrection.
That's why 1John 3:9 says the one who is born of God is not able to sin. Paul said as much in Romans 7 - it is no longer I who do it, but sin in me; that is, in my flesh (body). But who will save me from this body of death? Christ.
Go back to Romans 5. Having been (past) justified by His blood, we shall be (future) "saved" by His life (resurrection)
Read 2Cor 4-5. There's a distinction between the inner man, who is being strengthened day by day, and the outer man which is perishing.
Neglecting this distinction forces a view of righteousness which hinges on behavior. Or it hinges on a "symbolic" imputation, which reduces the blood of Christ to being no better than that of an animal
