1 Corinthians 3:1-7

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! I fed you with milk, not solid food; for you were not yet able to receive it. Even now you are still not ready. 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]? For when one of you says, “I am [a disciple] of Paul,” and another, “I am [a disciple] of Apollos,” are you not [proving yourselves unchanged, just] ordinary people? What then is Apollos? And what is Paul? Just servants through whom you believed [in Christ], even as the Lord appointed to each his task. I planted, Apollos watered, but God [all the while] was causing the growth. So neither is the one who plants nor the one who waters anything, but [only] God who causes the growth.
