Mat_21:16 "Do you hear what these children are saying?" they asked him. "Yes," replied Jesus, "have you never read, "'From the lips of children and infants you, Lord, have called forth your praise'?"
1Co_3:1 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.
1Co_14:20 Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults.
Eph_4:14 Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming.
