Romans 8:4 “…who walk after the flesh, but after the Spirit.” 1 Corinthians 3:3 “…are ye not carnal, and walk as men?” 2 Corinthians 10:3 “For though we walk in the flesh, we do not war after the flesh.” Galatians 5:17 “For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.” The New Testament etches a mark between the old nature and the new, between the flesh and the spirit (John 3:5,6).
