When Christian's pray, it's cuz they refuse to accept evil happening in this world. And God will use them as salt and light where it's most needed.

“He who passively accepts evil is as much involved in it as he who helps to perpetrate it. He who accepts evil without protesting against it is really cooperating with it.” ~ Martin Luther King, Jr.
