I speak in tongues on occasion. I am prone to think that it is the evidence of the Holy Spirt Baptism. I believe in the validity of a prayer language. Also, I have interpreted tongues and have spoken to foreigners in their languages including Hindi, Arabic, Mandarin, and Spanish. I've also sang in tongues.
