I totally agree with Perky and Twistedsketch.
The real Gift of Tongues is when the Holy Spirit of God gives us the utterance in a supernatural way and not merely our own utterances according to the verse below -
Acts 2:4 - And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
The verse below suggests another kind of Tongues manifestation wherein the people uttered words of another language which they themselves did not know but the people of that language recognised the words and praised God.
Acts 2:11 - Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God.
When i experienced the Baptism of the Holy Spirit, roughly a decade ago, it was a genuine supernatural experience but i did not recieve the Gift of Tongues at that time for i was not enthusiastic to recieve it. I had only asked God for the Filling of the Holy Spirit and not the Gift of Tongues.
Over the years, i had skeptics question the genuinity of my experience although i had a genuine filling of the Holy Spirit. This is because they always thought that the Baptism of the Holy Spirit should always be accompanied with the manifestation of the Gift of Tongues. God knows the Truth.
I think this misunderstanding, among some of us christians, is because of the lack of thorough knowledge of the Bible Scriptures.
