Apparently you are the one who does not see what is plainly written.
1 Corinthians 12:4 Now there are varieties of gifts, but the same Spirit; 5 and there are varieties of service, but the same Lord; 6 and there are varieties of activities, but it is the same God who empowers them all in everyone. 7 To each is given the manifestation of the Spirit for the common good. 8 For to one is given through the Spirit the utterance of wisdom, and to another the utterance of knowledge according to the same Spirit, 9 to another faith by the same Spirit, to another gifts of healing by the one Spirit, 10 to another the working of miracles, to another prophecy, to another the ability to distinguish between spirits, to another various kinds of tongues, to another the interpretation of tongues. 11 All these are empowered by one and the same Spirit, who apportions to each one individually as he wills.
Romans 12:4 Just as each of us has one body with many members, and not all members have the same
function, 5 so in Christ we who are many are one body, and each member belongs to one another.
6 We have different gifts according to the grace given us. If one’s gift is prophecy, let him
use it in proportion to his faith; 7 if it is serving, let him serve; if it is teaching, let him teach;
8 if it is encouraging, let him encourage; if it is giving, let him give generously; if it is leading,
let him lead with diligence; if it is showing mercy, let him do it cheerfully.
I wish that all of you could speak in tongues, but I would rather have you prophesy. He who prophesies
is greater than one who speaks in tongues, unless he interprets so that the church may be edified. 1 Cor 14:5
Scripture references speaking in tongues that edify an individual. This experience involves the individual speaking directly to God via his spirit. "For 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...He that speaketh in an unknown tongue edifieth himself;" 1 Cor 14:2,4
The other is the Spiritual gift of tongues for edification of the church. God speaks to the congregation through whomever He chooses via an unknown tongue. God then uses a person to operate in the Spirit gift of interpretation to present the message in a known language. This is a miraculous exchange orchestrated by God. Man is nothing more than a willing vessel used by God for a specific purpose.
Many fail to realize the difference and confusion is the unintended result that has the ability to scare people away. (1 Cor 14:23) “If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.
But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God. (1 Cor 14:27:28)
Notice Paul said "I
thank my God, I speak with tongues MORE than ye all:
(implying all pray in unknown tongues)
Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue." 1 Cor 14:18-19)
