New Defender's Study Bible Notes
3:2 not with meat. Compare Hebrews 5:12-14. Baby Christians are wonderful to see, just like baby people; but if they remain babies indefinitely, they become tragic to behold. Spiritual growth requires, first, the milk of the word (I Peter 2:2), but then soon they should begin to partake of the strength-building meat of the word (Jeremiah 15:16).
