Speaking in tounges is not evidence of salvation, it is evidence of the infilling of the Holy Spirit.
That mean ole Holy Spirt didn't fill me
when I accepted Jesus as my Savior on July
21 1985. I am going to have a talk with him about that.
Assembly of God would tell you that if you don't speak in tongues... you have not been filled with the holy spirit. And then the serious ones will quote the text that says if we're not filled with the spirit, that we are not truly saved.
You are just provolking a fight. Or was it too hard to read the next sentence he wrote?
Woah.
I accepted Jesus as my Savior that very same week!
Cool.............
And your question is better answered by a panel of "experts" from various denominations who have studied that sort of thing to exhaustion. I used to deal with that question, but it made my head hurt.
I finally decided to just allow God to be God and follow Him according to the Scriptures and what He would have me do.
