Thematic Bible: Who is immature

And I, brothers, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. I have fed you with milk, and not with solid food, for until now ye were not able to bear it, neither yet now are ye able. For ye are yet carnal: for whereas there is among you envying and strife and divisions, are ye not carnal and walk as men?

Of whom we have many things to say and difficult to declare, seeing ye are hard of hearing. For you should now be teaching others, if we look at the time, yet you need to be taught again which are the first elements of the oracles of God and are become such as have need of milk, and not of strong food. For any one that uses milk is not qualified in the word of righteousness, for he is a babe.
