The way I see it, any Christian can have this "speaking in tongues" if they want it. It is a shame that some Christians think that because people do not want it or have not got it then they are not saved, which is ridiculous.
This becomes available when someone is baptised by Holy Spirit, another huge mus-understood area and another area which is used by some people to elevate themselves above others.
I was sceptical at first myself, I did not even know if I had been baptised by Holy Spirit, I did not remember such an event, but it was a few years ago now that I was attending a series of talks and teaching on this subject, I went up at last day as I thought I had not been baptised by Holy Spirit, so people were being prayed over to be baptised, after we went through all the junk and issues that could be a block as to why, God showed me that I had, a quick vision as to the event some 25 years previous and I'm like "Oh yeh I remember that now".
After that I just realised I could speak in this so tried, it just came out natural like, it was listened to, prayed about and had it confirmed it was Holy Spirit at work, not some other spirit influencing me.
So yes, there you have it, if people do not want to use this, then I have no problem with it, what I do have a problem with is some people using it as something to elevate their standing and status.
