That was one of my major problems with them as well. I suspect that tongues is emphasized because it is the easiest one to fake, and because they claim that it doesn’t have to be an actual Earthly language.
I do see lots of scripture in favor of spiritual gifts being still active, and not ceasing; however, I just don’t think they’re the real deal. I also suspect a great deal of gifts... are gifts like wisdom, ability to teach the Gospel, things of that nature. Things that aren’t flashy like, for example, calling fire down form heaven, but just as valid as the gifts of prophecy or any of the ones they covet.
Of all the gifts, if I had a choice, it would be discernment.
Above all else, I want to know what is of God and what is not.
