1 Cor 3:1-9

3:1 Brothers, I could not address you as spiritual but as worldly — mere infants in Christ. 2 I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready. 3 You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere men? 4 For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not mere men?

5 What, after all, is Apollos? And what is Paul? Only servants, through whom you came to believe — as the Lord has assigned to each his task. 6 I planted the seed, Apollos watered it, but God made it grow. 7 So neither he who plants nor he who waters is anything, but only God, who makes things grow. 8 The man who plants and the man who waters have one purpose, and each will be rewarded according to his own labor. 9 For we are God’s fellow workers; you are God’s field, God’s building.
