For a Pentecostal or Charismatic who believes that they have the gift of tongues just as in Acts, like the Azusa St. folk did, the question is: who got saved? At Pentecost, 3000 people got saved through the tongues/languages ministry. In the vast majority of cases with modern tongues speakers, no one gets saved. They just feel good. That's not Bible Christianity.
Now, rockytopva, our thread founder, appears to be strictly following the Azusa St. principles. Let me ask you directly, rockytopva, do you believe that your tongues are actual languages that can be used to win people to Christ? That is what the Azusa St. folk believed. Buy the book I referenced before, Azusa Stree and Beyond, ed. by L. Grant McClung, Jr. It is a book of essays about the Azusa St. incident (I hesitate to call it a genuine revival) written by Pentecostal/Charismatic scholars, not by opponents of the movement. If you seek truth, it will open your eyes.
Another great book for the true seeker is I Once Spoke in Tongues, by a former Pentecostal Wayne A. Robinson. Here are some quotes from that book.
"As Dave Wilkerson, the well-known minister to addicts, has reported, tongues takes the place of narcotics for many former addicts. For many charismatic Christians, tongues is a spiritual high" (p. 98).
"One of the ironies which blemish the Christian religion is that where the most religious zeal is displayed, the mission of Jesus is often of least concern" (p. 99). So if the Great Commission is not being fulfilled, tongues are useless.
"Worn as a badge of identification, tongues results in walls of division, mistrust, and resentment. Much of the strong negative feeling that many church people hold against tongues speaking can be traced to this misuse" (p. 123). I can testify to this. Charismatics attacked my soul-winning ministry in Japan three times. The un-Christian zeal of those Japanese tongues speakers who never won a soul to Christ completely repelled me.
