(2Co 5:16) “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.” The new person (saved) in Christ is now a spirit being, which explains what is meant in Verse 16. I used to “know” of Jesus as a lost person, but when I repented and embraced Him as Savior, He gave me spirit-life allowing me to know Him in a far more intimate way.
