But and if ye suffer for righteousness' sake, happy are ye . . These references clearly demonstrate that those who faithfully serve the Lord sometimes suffer. So, we see that both righteous and unrighteous people suffer. We must never envy the ungodly, thinking that maybe their life really is better and happier, and we must never accuse God of being unfair. For I was envious at the foolish, when I saw the prosperity of the wicked.
Some people suffer because of mistakes that they themselves make.
Others try to commit suicide with a knife, but they fail. The result might be that they will have physical pain until the day of their death. One might drive while he is drunk and as a result have an accident that leaves him crippled. His pain and inconvenience would be a form of suffering, but he must admit that he is suffering in this fashion because of his own terrible mistake. A man might suffer in poverty because he lost all of his money gambling.
