Did prayer stop the tornado?

I personally don't think that God most frequently alters the laws of nature that He established. That seems counter-intuitive. I do think that someone may be inspired of what to do in order to avoid devastating effects-- like going to a safe place.  Ill be honest-- I don't know how prayer works, but I do know that praying is an activity that has tremendous positive psychological effects and enhances positive moods. That alone-- regardless of any other outcome, is enough reason for me to pray.

Lets say I prayed not to be hit by the tornado and I suddenly felt calm. Is this because the tornado wasn't going to hit me? Or is it because if it does hit me, its my time to die and being dead is not really a bad thing? Or is it because speaking to God is a soothing activity that God encourages for his children to engage in because it helps them accept the things that they cant control? I don't know. I just know that God asks me to do it and I find greater joy in life when I do. Prayer is for everyone. Whether thanking God or asking for help. In both instances, I am infused with greater peace and joy. I have found that the blessing of prayer is inherent in the activity itself. I think God often works this way. Prayer is for us; for our benefit and I thank God for it.

Did prayer stop the Tornado? Maybe only the one in my heart, by helping me to accept the things I cannot control and to improve upon the things I can.
