Complaining can mean different things in different contexts. Those who complain could be expressing grief or sorrow or accusing someone of an offense. In that context, there is nothing overtly sinful about complaining. As long as the expression of grief or accusation of wrongdoing conforms to biblical guidelines, the complaint is appropriate. After all, the Bible contains a book called Lamentations, and many of the psalms contain “complaints”—utterances of grief over a dire situation. However, complaining can also take the form of fault-finding, murmuring, griping, or grumbling, in which case it is wrong.
