The best way I can answer some of your questions is to share what happened to me at this church, I was openly mocked, humiliated, and torn down. At first I didn't realize what was happening because it was so subtle. I am a writer and when I made known my desire to write a book, I was laughed at "who, you! You can't possibly be serious! " I also have always had a heart for the mission field, but every opportunity that presented itself, my "leaders" shot me down, everything I did was a sin, I couldn't do anything right, even the way I walk is sin, I was told I walk too seductive and the devil is using me to bring down men of God, I have an autoimmune disease and I was told I'm sick because there is secret sin in my heart, everyone that leaves the church and later wants to come back gets shunned, if you talk about leaving, your told that you were never truly saved, and watch out or God might strike you down for leaving His church, there is big talk about commitment, but it's more about being committed to the church rather than Jesus, there's even a worship song praising the church, other churches are openly mocked, they call them "the church of the chosen frozen" if you go to your leaders with any concerns your told "your not spiritually mature, if you feel the need to question our authority "because your leaders have ultimate authority over your life. At the end of some sermons, the pastor will tell the congregation "everyone that can speak in tongues, speak them now " I have always had a problem with this, because speaking in tongues should be led by the holy spirit, not by man. This is just the tip of what goes on.
22 Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe. - 1 Corinthians 14:22 (KJV)
And it is the Jews which require a sign (See 1 Cor. 1:22).
Therefore the whole modern tongues movement is false.
A lot of times, these "tongues" that the Charismatics and pentecostals are blibbering and blabbering is all made up.
Tongues are simply languages. If you speak English, well you speak only one tongue. But if you speak English, Spanish, and Chinese, well then you speak in three tongues.
