I have to admit that this "tongues" topic has proven to be a stumbling block to me. I will never try to be or do something that isn't natural. If it doesn't come to me from the Holy Spirit I won't fake it in order to fit in with (most) everyone else. God bless.
Interesting statements that bring something to mind. The best fodder for cults are people who feel the need to fit in, first, who you can get to swallow anything or act out anything, as long as their social deficits are met. People can have strong herd instincts. It's a legitimate point to wonder how many people would take up faking tongues just to fit in with perhaps the also faking babbler next to them, like a snowball going downhill, just to be socially acceptable to the in-crowd. You, yourself, appear to be cognizant of such pressure. It seems to me this could well be a red flag, that maybe the Holy Spirit is already speaking to you about fakery. (I'd also have to ask how this congregation is so "tongues-ie" above others. If as has been equated in Romans gifts of the Spirit are like different parts of one body, why does this church have, say, so many left arms?) I do know, when it's of the Spirit of God, anything, I've never felt confused, perplexed, skeptical the teaching, etc. In other words, such questions popping up in my soul seem to always indicate something is wrong, something is not harmonious of God, who is not the author of vexation and confusion. Anyway, God bless and keep you in this!
1 Corinthians 14:33 For God is not the author of confusion, but of peace, as in all churches of the saints.
