I have respect for Andrew Strom - he is a Pentecostal pastor originally from New Zealand and preaches sound doctrine.
Fortunately I am Pentecostal and not charismatic.
Worth pointing out that most, if not all, the weird and wonderful mutations of Christianity begin in the U.S.A.
As an outsider I have observed that religion is somewhat strange in America.
So then you do not trust in the idea of sign gifts like a charismatic?
What kind of Pentecostal are you?
Where did your idea of tongues originate ? Isiah 28 the foundation of the doctrine or law revisited spoken of in 1 Corinthians 14 :28 ?
21 In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord.
