1 Corinthians 3:1, 10-11, 2-9

And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.

According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon. For other foundation can no man lay than that is laid, which is Jesus Christ.

I have fed you with milk, and not with meat: for hitherto 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? For while one saith, I am of Paul; and another, I am of Apol´los; are ye not carnal? Who then is Paul, and who is Apol´los, but ministers by whom ye believed, even as the Lord gave to every man? I have planted, Apol´los watered; but God gave the increase. So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labor. For we are laborers together with God: ye are God's husbandry, ye are God's building.
