For those who speak in tongues, please memorize 1 Cor 14 and make sure an interpreter is present whenEVER tongues is spoken in public. When speaking in tongues in private, just remember what Paul said about that:
1 Cor 14:4 - Anyone who speaks in a tongue edifies themselves, but the one who prophesies edifies the church. iow, no benefit to others.
v.5 - I would like every one of you to speak in tongues, but I would rather have you prophesy. The one who prophesies is greater than the one who speaks in tongues, unless someone interprets, so that the church may be edified.
v.9 - So it is with you. Unless you speak intelligible words with your tongue, how will anyone know what you are saying? You will just be speaking into the air. iow, no profit to others.
v.12 - So it is with you. Since you are eager for gifts of the Spirit, try to excel in those that build up the church.
v.14 - For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
iow, the speaker has no idea what they are praying when praying in a tongue.
