Ok...? But that's not what the scriptures are saying here..its a true point but not the intention of the passage being discussed. "he became sin" who knew no sin...is saying more than He was a sin offering after the example of the law.
If it was saying He was a sin offering..the following point of Him knowing no sin, would not have been made...think about it.
We need to understand the types and anti-types in the Bible.
The imputation of sin to Jesus Christ was typified in the Old Testament sacrificial system, where the sins of the offerer were symbolically transferred to the animal victim.
If we take at face value what Paul said then Jesus found himself in the same position as anyone else born in sin. This makes Christ a sinner without being born in sin or ever sinning. How can a sinner take away sin? It's utter blasphemy!
Albert Barnes notes on 2 Cor. 5:21, If the declaration that he was made “sin” hamartian (NT:266) does not mean that he was sin itself, or a sinner, or guilty, then it must mean that he was a sin-offering-an offering or a sacrifice for sin; and this is the interpretation which is now generally adopted by expositors; or it must be taken as an abstract for the concrete, and mean that God
treated him as if he were a sinner. The former interpretation, that it means that God made him a sin-offering,”
2 Cor. 5:21 “He made him who knew no sin (who was innocent), a sin-offering for us. The word hamartia (NT:266) occurs here twice: in the first place it means sin, i.e. transgression and guilt; and of Christ it is said, He knew no sin, i.e. was innocent.
In the second place, it signifies a sin-offering, or sacrifice for sin, and answers to the chaTa'ah (OT:2401) and chaTa'at (OT:2401) of the Hebrew text; which signifies both sin and sin-offering in a great variety of places in the Pentateuch.
2 Cor. 5:21, If the declaration that he was made “sin” hamartian (NT:266) does not mean that he was sin itself, or a sinner, or guilty, then it must mean that he was a sin-offering-an offering or a sacrifice for sin; and means that God treated him as if he were a sinner.
2 Cor. 5:21 Locke renders this: probably expressing the true sense, “For God hath made him subject to suffering and death, the punishment and consequence of sin, as if he had been a sinner, though he were guilty of no sin.”
Jesus would have been the Azazel from the Hebrew i.e."an entire removal" or "sending away) (Lev.16:8-10).
