Charles Spurgeon Commentary 2 Corinthians 5:16

"Wherefore we henceforth know no man after the flesh: even though we have known Christ after the flesh, yet now we know [him so] no more." — 2 Corinthians 5:16 (ASV)

Therefore, from now on, we know no one after the flesh: yes, though we have known Christ after the flesh, yet now, from now on, we know him no more.

He is gone back to glory, so our object is not to win a kingdom for him anywhere upon earth. Our aim now is spiritual, the proclamation of his truth, the winning of a kingdom for him in the hearts of men.

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.

We do not see Christ with our natural eyes, we do not hear his voice with our natural ears, he is to us now a spiritual Personage, who communicates with our spirits through his own ever-blessed Spirit.
