Why does everyone focus so much on tongues? What about the other gifts of the Spirit? Prophecy, Healing, miracles, discerning spirits, etc.
My guess is Tongues is the only one of the above you can fake and not easily disprove.
Counterfeits and fakery abound in Christianity of every stripe and denomination.
Probably people in every congregation are faking that they are earnest, confessed up, repented up, loving God wholly, neighbors as selves, doing unto others types of Christians
when they clearly are not.
Charismatic groups have no monopoly on counterfeits or fakery at all to any degree.
I think it's cheeky to pretend that they do.
