Speaking in Tongues?

When reading the New Testament, I see a correlation between speaking in tongues and receiving the Holy Spirit. All Scripture is profitable for teaching and training in righteousness, so what am I (or any Christ-following individual) supposed to draw from this correlation?

Some denominations assert that the correlation between tongues and receiving the Holy Spirit existed only during the early church era, when Christianity was in its infancy and was supernaturally validated by tongues when it spread to a new geographical region. Other denominations say that speaking in tongues is a sign of being accepted into the body of Christ through the baptism of the Holy Spirit, and that a person can't possibly be a true Christian without having spoken in tongues. Still other denominations say that speaking in tongues comes as a result of submitting oneself to God, being completely filled with the Holy Spirit, and experiencing the full power that God intended for His children to have on earth. So, we still have the question: what are we to think of speaking in tongues?

Well, my husband and I have become more and more curious about this, so we decided to do an experiment. We followed the instructions of a "Practical Guide to Being Filled with the Holy Spirit" (see the full article here) to see if we would start speaking in tongues spontaneously. Interestingly, Josh and I both had very clear phrases that came to our minds (in a language we didn't know... and we suspected that our minds may have just made up the words in anticipation of speaking in tongues). This happened to Josh before, actually, and at that time he looked up the phrase and found out that the words were Hebrew. So, we decided to do look up the words, and sure enough, they were Hebrew. I also had a couple more phrases come to mind later that day and the next. Here are all the phrases that came to mind after asking the Holy Spirit to fill me (I'll spell them as best I can):

Shekem malak -- Ala asa tum (or tom) -- Oto kaba

So, I don't know if this is speaking in tongues or not, but if it is, it's nothing like I expected it to be. I will keep pursuing God about this and see what happens!
