But now, brethren, if I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?

So also you, unless you utter by the tongue speech that is clear, how will it be known what is spoken? For you will be speaking into the air.

I am not speaking these things according to human judgment, am I? Or does not the Law also say these things?

Or is He speaking altogether for our sake? Yes, for our sake it was written, because the plowman ought to plow in hope, and the thresher to thresh in hope of sharing the crops.

Therefore I make known to you that no one speaking by the Spirit of God says, “Jesus is accursed”; and no one can say, “Jesus is Lord,” except by the Holy Spirit.
