He that speaks in an unknown tongue edifies himself; but he that prophesies edifies the church.
And these signs shall follow them that believe; In my name shall they cast out demons; they shall speak with new tongues;
But he that prophesies speaks unto men to edification, and exhortation, and comfort.
I would that you all spoke with tongues, but rather that you prophesied: for greater is he that prophesies than he that speaks with tongues, except he interpret, that the church may receive edifying.
How is it then, brethren? when you come together, every one of you has a psalm, has a doctrine, has a tongue, has a revelation, has an interpretation. Let all things be done unto edifying.
Let us therefore follow after the things which make for peace, and things with which one may edify another.
And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not love, I am nothing.
Even so you, since you are zealous of spiritual gifts, seek that you may excel to the edifying of the church.
For you verily give thanks well, but the other is not edified.
Therefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serves not for them that believe not, but for them that believe.
