1 Follow after love; yet desire earnestly spiritual [gifts], but rather that ye may prophesy. 2 For he that speaketh in a tongue speaketh not unto men, but unto God; for no man understandeth; but in the spirit he speaketh mysteries. 3 But he that prophesieth speaketh unto men edification, and exhortation, and consolation. 4 He that speaketh in a tongue edifieth himself; but he that prophesieth edifieth the church. 5 Now I would have you all speak with tongues, but rather that ye should prophesy: and greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
6 But now, brethren, if I come unto you speaking with tongues, what shall I profit you, unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching? 7 Even things without life, giving a voice, whether pipe or harp, if they give not a distinction in the sounds, how shall it be known what is piped or harped? 8 For if the trumpet give an uncertain voice, who shall prepare himself for war? 9 So also ye, unless ye utter by the tongue speech easy to understood, how shall it be known what is spoken? for ye will be speaking into the air. 10 There are, it may be, so many kinds of voices in the world, and no [kind] is without signification. 11 If then I know not the meaning of the voice, I shall be to him that speaketh a barbarian, and he that speaketh will be a barbarian unto me. 12 So also ye, since ye are zealous of spiritual [gifts], seek that ye may abound unto the edifying of the church.
13 Wherefore let him that speaketh in a tongue pray that he may interpret. 14 For if I pray in a tongue, my spirit prayeth, but my understanding is unfruitful. 15 What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. 16 Else if thou bless with the spirit, how shall he that filleth the place of the unlearned say the Amen at thy giving of thanks, seeing he knoweth not what thou sayest? 17 For thou verily givest thanks well, but the other is not edified. 18 I thank God, I speak with tongues more than you all: 19 howbeit in the church I had rather speak five words with my understanding, that I might instruct others also, than ten thousand words in a tongue.
20 Brethren, be not children in mind: yet in malice be ye babes, but in mind be men. 21 In the law it is written, By men of strange tongues and by the lips of strangers will I speak unto this people; and not even thus will they hear me, saith the Lord. 22 Wherefore tongues are for a sign, not to them that believe, but to the unbelieving: but prophesying [is for a sign], not to the unbelieving, but to them that believe. 23 If therefore the whole church be assembled together and all speak with tongues, and there come in men unlearned or unbelieving, will they not say that ye are mad? 24 But if all prophesy, and there come in one unbelieving or unlearned, he is reproved by all, he is judged by all; 25 the secrets of his heart are made manifest; and so he will fall down on his face and worship God, declaring that God is among you indeed.
