Let’s get something straight.
Anger is not a sin.
Jesus was pure. He didn’t sin, and yet, in Mark 11:15-25, Jesus is clearly angry with the people who are defiling God’s temple. This shows us that anger is not a sin, in and of itself. There is such a thing as “righteous anger”.
This is not righteous anger:
In a much later scene, the Hulk does have the good type of anger, when he’s fighting Loki and the Chitauri. Now, like I said before, anger is not a sin. It’s what you do with your anger that makes you sin. We’ll be talking about that in a later post, so, for now, just remember; even Jesus got angry. Anger is not necessarily a sin, as long as you’re angry at the right thing.
