1 Corinthians 14:20-25 Truth Matures The Mind

Brothers and sisters, do not be children in your thinking; yet in evil be infants, but in your thinking be mature.  In the [i]Law it is written: “By men of strange tongues and by the lips of strangers I will speak to this people, and even so they will not listen to Me,” says the Lord.  So then, tongues are for a sign, not to those who believe but to unbelievers; but prophecy is not for unbelievers, but for those who believe. 23 Therefore if the whole church gathers together and all the people speak in tongues, and [j]outsiders or unbelievers enter, will they not say that you are insane?  But if all prophesy, and an unbeliever or an [k]outsider enters, he is convicted by all, he is called to account by all;  the secrets of his heart are disclosed; and so he will fall on his face and worship God, declaring that God is certainly among you.
