1 Corinthians 14
18 Ref I give praise to God that I am able to make use of tongues more than you all:
19 Ref But in the church it would be better for me to make use of five words of which the sense was clear, so that others might have profit, than ten thousand words in a strange tongue.
20 Ref My brothers, do not be children in mind: in evil be as little children, but in mind be of full growth.
21 Ref In the law it is said, By men of other tongues and by strange lips will my words come to this people; and not even so will they give ear to me, says the Lord.
22 Ref For this reason tongues are for a sign, not to those who have faith, but to those who have not: but the prophet's word is for those who have faith, and not for the rest who have not.
23 Ref If, then, the church has come together, and all are using tongues, and there come in men without knowledge or faith, will they not say that you are unbalanced?
