funny, i learned this in Sunday school ( Catholic ) this past sunday. speaking in tongue is because its more effective than just praying in english or whatever language and i dont know if its because satan cant hear it, but i had spoke in tongue sunday and its suppose to be much more powerful, very powerful in fact

-we had spoke in tongue to help heal my friends leg and i dont know if it really worked but i heard lots of stories.. i'll see if it really helped my friend and update sunday.
