1 Corinthians 13:11

1 Corinthians 14:20 NIV
Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults.

1 Corinthians 3:1-2 NIV
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. I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready.
