Jesus is an example to Christians about how to remain peaceful when other people are mistreating us. Jesus allowed himself to be crucified without even resisting.
However, there is also an instance recorded in the Bible where the usually calm and serene Jesus became provoked to the point of physical violence.
When it was almost time for the Jewish Passover, Jesus went up to Jerusalem. 14 In the temple courts he found people selling cattle, sheep and doves, and others sitting at tables exchanging money. 15 So he made a whip out of cords, and drove all from the temple courts, both sheep and cattle; he scattered the coins of the money changers and overturned their tables. 16 To those who sold doves he said, “Get these out of here! Stop turning my Father’s house into a market!” 17 His disciples remembered that it is written: “Zeal for your house will consume me.” (John 2:13-17 NIV)
Jesus’ anger here is well justified. Although there was nothing wrong with the merchants selling items for sacrifice to pilgrims from far away, it should have not been done in the temple. This was sacrilege against the one true God who created the universe. Furthermore, it is likely that some of them were boosting their prices and taking advantage of the unsuspecting foreigners. This kind of action is despicable wherever it is carried out, but it is even worse when it is done in the house of God!
