Thematic Bible: Who is immature

As for me, brothers, I could not talk to you as spiritual men, but as to creatures of flesh, mere babes in Christ. I fed you milk, not meat; for you were unable to bear it. You are not able even now, for you are still unspiritual. While there is among you jealousy and strife, are you not still unspiritual, and behaving like worldlings?

Concerning him I have much to say, and much that is hard to make clear to you, because you have grown dull of hearing. And this too, although you ought by this time to be teaching others, you are still needing some one to teach you the very rudiments of divine revelation. You need milk, not solid food. For every one who feeds on milk is inexperienced in the word of righteousness. He is still an infant.
