It seems to me that the world is sooooo angry. Just recently in three different cities, two strangers have started arguing in a parking lot and in all three cases, while yelling at one another, someone pulls out a gun and shots the other one. And the person dies. This is the ultimate of fully venting one’s anger.
Anger in itself is not a sin…Jesus got angry and He was without sin. It becomes a sin when we do not hold that anger in check…when we vent it on those around us. True maturity is demonstrated when one, despite the justified situation, is meek rather than wrathful.
