“We live
As human beings,
But we do not wage war
According to human standards.”
Ἐν σαρκὶ γὰρ περιπατοῦντες οὐ κατὰ σάρκα στρατευόμεθα,
Paul said that we live or walk around (γὰρ περιπατοῦντες) as human beings (Ἐν σαρκὶ), but we do not wage war (στρατευόμεθα) according to human standards (οὐ κατὰ σάρκα). Paul admitted that he was a human or in the flesh like everyone else. However, he was engaged in a war against evil forces where he did not use human weapons to battle them. This was a more serious spiritual war. Have you ever been in a war?
