2 Corinthians 10:3-6 NKJV For though we walk in the flesh, we do not war according to the flesh. [4] For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, [5] casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, [6] and being ready to punish all disobedience when your obedience is fulfilled.
“we walk in the flesh” is talking about being human, that is flesh and blood, not carnality.
We find another example of this sort of language that does not indicate carnality in Ezekiel 36:26 NKJV I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh.
