1 Corinthians 14 (King James Version)
1 Corinthians 14
1Follow after charity, and desire spiritual gifts, but rather that ye may prophesy.
2For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
3But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
4He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
5I
would that ye all spake with tongues but rather that ye prophesied: for
greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
6Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?
7And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?
8For if the trumpet give an uncertain sound, who shall prepare himself to the battle?
9So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air.
10There are, it may be, so many kinds of voices in the world, and none of them is without signification.
11Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me.
12Even so ye, forasmuch as ye are zealous of spiritual gifts,
seek that ye may excel to the edifying of the church.
13Wherefore let him that speaketh in an unknown tongue pray that he may interpret.
14For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful.
Now why would you want to speak in tongues and your understanding be unfruitful...your spriit is praying but its not doing you any good because you want understand it...your missing the Whole Point stop reading certain scriptures and read the whole chapter.. read 1 Corithians 14 all the way through,stop picking and choosing what you were taught to believe..Read it as a whole
