'Of the Flesh' in the Bible

However, brothers and sisters, I could not talk to you as to spiritual people, but [only] as to worldly people [dominated by human nature], mere infants [in the new life] in Christ!

You are still worldly [controlled by ordinary impulses, the sinful capacity]. For as long as there is jealousy and strife and discord among you, are you not unspiritual, and are you not walking like ordinary men [unchanged by faith]?
