I have an issue too when it comes to tongues, I was prayed for many years ago to receive the Holy Spirit, and I did get a small prayer language (a few words that if I say too loudly I cannot hear the others so I end up mumbling them). Recently I was blessed to be next to my Brother who got filled a few days after conversion and he just went of on one, you know? about the same time the preacher was talking about people who had a 'prayer language' but that was not necessarily the Holy Spirit, just somethine they had picked up, or copied and, at worst, a fake. My dilema, did I have the Holy Spirit or not? Well that was early last year, this year I have been prayed for numerous times with ppl all around me being filled and I just felt nothing, some ppl told me the bit of tongues I had was good and with use they would increase, others told me they were not. Of course I took it to God, and the weird thing is I have a peace about it though I have no clear answer. God has spoken to me (mostly to tell me off, lovingly) and with this encouragement I believe I have a 'measure' of the Spirit, He is a still small voice that is there when you listen and want direction, I often hear Him tell me 'do some praying now, don't go to bed yet'. I believe I am getting closer to God, I am making the effort to pray more, read and learn more, seek His face etc, I guess when He wants to He will give me what I think I need: a noticable filling of the Spirit complete with tongues, but even without, I will continue to seek His face and trust Him.This has not answered your question I know, but don't get hung up on what others are upto, just trust and obey God, He is our all in all.
