1 Corinthians 3:1-3 NIV

[1] Brothers and sisters, I could not address you as people who live by the Spirit but as people who are still 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 humans?
