Why do bad things happen to good people, and good things to bad people?

Why do bad things happen to good people? It is a question, I think, most of us have asked ourselves rather often, particularly when bad things happen to people we love and care about, or to ourselves. Well, most often it is not actually a question, I think, as much as an outcry; it is not really that we are looking for explanations or other kinds of answers. In asking, we air our frustration in order to alleviate our emotional agony.
The answer Holy Scripture gives, though, and as such the Christian faith, has much to give by way of alleviating emotional agony; well, it does for those who have ears to hear.
