How Close Christ Came to Sinful Humanity and to Sin

For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (2 Co 5:21 ESV)

The fact is that the Lord Jesus came not only into the closest relation to sinful humanity that was possible for him to come without becoming himself sinful, but he also came into the closest relation to sin that it was possible for him to come without thereby becoming himself sinful.  John Murray, Collected Works, 1:38
