What a silly question. If you haven't, then why did you post a bunch of irrelevant verbiage?
the praying in tongues is found in 1cor chapter 14. It does not matter if we see any benefit in it, it only matters that it is in the word of God, and is it for today? I believe this gift is as all are. The origin of this gift is the Holy Spirit. That is what 1cor chapter 12 is stating.
What if we see it as judgement on those who mock God and it warns us? That's a benefit .
Chapter 14 informs us of the law God mocking those who mock prophecy .The tongue of God. They would be the ones that forfeit the foundation of the law (Isaiah 28) and keep the tradition of corrupted mankind. Seeking after wonderments through signs men perform, self edification .(Look I did it)
