1 Corinthians 14:20-25

Twentieth_Century(i) 20 Brothers, do not show yourselves children in understanding. In wickedness be infants, but in understanding show yourselves men. 21 It is said in the Law-'In strange tongues and by the lips of strangers will I speak to this people, but even then they will not listen to me, says the Lord.' 22 Therefore the gift of the 'tongues' is intended as a sign, not for those who believe in Christ, but for those who do not, while the gift of preaching is intended as a sign, not for those who do not believe in Christ, but for those who do. 23 So, when the whole Church meets, if all present use the gift of 'tongues,' and some men who are without the gift, or who are unbelievers, come in, will not they say that you are mad? 24 While, if all those present use the gift of preaching, and an unbeliever, or a man without the gift, comes in, he is convinced of his sinfulness by them all, he is called to account by them all; 25 The secrets of his heart are revealed, and then, throwing himself on his face, he will worship God, and declare 'God is indeed among you!'
