Job Chapter 8 You suffer because of God's Justice

Bildad's response to Job. Most people—believers and nonbelievers alike—think they are fairly good people. They may do a few things wrong here and there, but in general they consider themselves good people. They reason, then, that good things should happen to them, at least for the most part. They may suffer some hardships along the way, accepting that difficulties and problems are a part of life. Nevertheless, their belief is that they deserve good things. This reasoning, like the arguments of Job's friends, is based on the idea of divine justice or retribution, that is, that good things happen to good people and bad things happen to bad people. The problem with this thinking is simply that it does not hold up under close scrutiny. It is not true for everyone; nor is it true all the time. Many people suffer for no apparent reason, and there is no way to explain their suffering.
