The Purity of Christ as Mediator and Sacrifice
Here is the Lord Jesus Christ I know, and am convinced Scripture testifies to.
He died a completely obedient man in Himself.
He was holy, innocent, undefiled, separate from sinners and remained obedient all the way to His death, even the death of the cross [Philippians 2:8–not toward His death but all the way up to and including death. He was obedient all the way to His death, not a rebel in His death].
He never at any time began to hate His Father.
He suffered FOR sins, the Just One FOR the unjust, not AS sin but FOR sin. At no time was He ever tainted with our sin. But as our Great Mediator, perfect and innocent in Himself, He willingly accepted all our sins that were imputed to His account and offered His perfect self as an offering for our sins.
He CALLED those sins His own. He willingly owned them all, took full responsibility for them and bore them upon Himself and carried them away making and end of sin for all His people.
Only the God-man could accomplish this.
Sin could not be infused with His divine nature, else He ceased to be God on the cross. In the light of all other Scripture, the only possible view of 2 Corinthians 5:21 is strictly judicial transfer of sin to Christ. This is what Paul meant when he said, “He was made sin FOR us, who KNEW NO SIN.” Would to God that men would interpret Scripture with Scripture.
