hmm, i find my church is full into 'speaking in tongues' when you receive the holy spirit. It's all great and that, but I personally don't believe that just because you're blessed with the holy spirit means you will suddenly be able to speak in tongues. I believe that we're all blessed with a different gift of the spirit. Most of us will never speak in tongues. I don't think it is superior above the rest, at all.
tbh, what's more important to me is the faith, not religion. Religion won't save you. Faith alone, on the other hand, will. So, in saying that, I do not feel it essential to attend church, Others disagree with me.
