Know no one after the flesh

LET’S NOT KNOW ANY MAN AFTER THE FLESH ANYMORE.
Our firm decision is to work from this focused center: One man died for everyone. That puts everyone in the same boat. He included everyone in his death so that everyone could also be included in his life, a resurrection life, a far better life than people ever lived on their own. [16] Because of this decision we don’t evaluate people by what they have or how they look. We looked at the Messiah that way once and got it all wrong, as you know. We certainly don’t look at him that way anymore. Now we look inside, and what we see is that anyone united with the Messiah gets a fresh start, is created new. The old life is gone; a new life burgeons!
2 Corinthians 5:14-17 MSG

…[T]he love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead: [15] And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again. [16] Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more. [17] Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
