'Terrible' in the Bible

I dedicated myself to using wisdom for study and discovery of everything that is done under heaven. God uses terrible things so human beings will struggle with life.

Consider someone who is alone, having neither son nor brother. There is no end to all of his work, and he is never satisfied with wealth. "So for whom do I work," he asks, "and deprive myself of pleasure?" This, too, is pointless and a terrible tragedy.
