There are two things a person should never get angry at, what they can help and what they cannot. (Plato, ancient Greek philosopher))
Life is full of errors, faux pax, and just plain mistakes. They will happen, so how do we react to them? We could get mad, but Plato suggests if we could have helped it, we shouldn’t be angry. It would be better just to correct the error and do better. If we couldn’t help it—it wasn’t our fault, then why should we be angry, we’ll not be blamed? That should help us avoid a lot of anger.
And don’t sin by letting anger control you. Don’t let the sun go down while you are still angry, for anger gives a foothold to the devil (Ephesians 4:26-27).
