Venting is that thing people (like me) do when something bad or annoying has happened. It usually involves someone else and how they made your life much harder and now all these things are going wrong (read “not like I wanted them to go”). And it normally coincides with some other significant life event and feels too much.
So you go and “get it off your chest”, or “vent”. You might even call it “processing”.
But what you’re really doing is either grumbling against God, slander or gossiping. Possibly all three.
Do you really need to get it off your chest? Really?
Well, have your tried telling God how you feel? Actually how you feel? No? Might it be because what you want to say isn’t very godly?
If you wouldn’t say it to God, don’t say it to anyone.
