What Does the Bible Say About Suffering‪?‬

If God is all-powerful and all-loving, why doesn't he do something about the pain and sorrow being experienced by the people he supposedly loves? How can he wipe hundreds of thousands of people out in earthquakes, tsunamis, floods and famines? Why doesn't he stop war, terrorism, and child abuse? Why doesn't he do something about the evil that lurks in the hearts of all of us? Well, he has.
