day no. 14,958: slander is confessing the sins of others

Ephesians 4:31-32
Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice.32 Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.

Slander is using your mouth to run someone else down because you think they are delinquent in confessing their own sins. In your kindness, you take it upon yourself to confess their sins for them. This benevolence is entirely unChristian. Paul here equates it with bitterness, wrath, anger, clamor and malice. It is the fruit of bitter roots, the equivalent of vengeance, is fueled by the anger of man, aims at filling peaceful air with loud noises and desires to tear down rather than build up. It is not for the benefit of the other person that you confess their sins. You are not confessing on their behalf so that they might go free, you are openly confessing their sins in order to enslave them and bind them to them, to identify them by the sins.

This is NOT how God in Christ identifies you! In Christ, He looks for ways to be kind. You are commanded to now do the same for those you may be tempted to be embittered toward, anxious to take vengeance upon, etc...
