Well "my spirit" is not the Holy Spirit. According to the common teaching it is supposed to be the Holy Spirit that is speaking when one prays or speaks in tongues. I do believe that the spirit of man is quite difficult to manage and capable of many things similar to the Holy Spirit.Paul wrote, "For if I pray in a tongue, my spirit prays, but my mind is unfruitful. So what shall I do? I will pray with my spirit, but I will also pray with my understanding; I will sing with my spirit, but I will also sing with my understanding." The context clearly indicates praying in a tongue unknown to Paul. "Unknown" is relative to the one speaking and those hearing, rather than being an absolute adjective.
If you are praising God with your mind, heart, and natural language, and you switch to tongues, which makes more sense... adoring or cursing?
