1 Corinthians 3:12

Now if any man build upon this foundation It must be remembered that it is not the conduct of Christians, however applicable the principles here enunciated may be to it, but the doctrine of teachers which is spoken of here. The materials mentioned are of two classes, those that will endure fire, and those that will not. We may dismiss from our consideration such preaching as is dictated by vain-glory or self-interest, for the simple reason that it is not building upon Christ at all. The two kinds of preaching thus become, on the one hand that which leads to permanent results, the glory of God and the real well-being of man; and on the other, that which, though the offspring of a genuine zeal, is not according to knowledge.
