1 Corinthians 3:4-7

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.
