How Will Anybody Catch the Melody?

1 Corinthians 14:20-25 NASB
20 Brethren, do not be children in your thinking; yet in evil be infants, but in your thinking be mature. 21 In the 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. 22 So then tongues are for a sign, not to those who believe but to unbelievers; but prophecy is for a sign, not to unbelievers but to those who believe. 23 Therefore if the whole church assembles together and all speak in tongues, and ungifted men or unbelievers enter, will they not say that you are mad? 24 But if all prophesy, and an unbeliever or an ungifted man enters, he is convicted by all, he is called to account by all; 25 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.
