Jesus was mean.
John 2:15: And when he had made a scourge of small cords, he drove them all out of the temple, and the sheep, and the oxen; and poured out the changers’ money, and overthrew the tables;
So, Jesus is sitting and making a whip. Probably made the disciples a bit curious. The only reason you make a whip is to whip something. In this case it was people.
People who were getting rich taking advantage of other people.
Moneychangers sold animals for sacrifice to extremely poor people at high prices. They also served as a currency exchange that charged high fees for their service. In short, they were using God’s work to profit off of poor families.
Jesus wouldn’t stand for it.
The only way to deal with wolves is harshly. So, he took their tables, flipped them over and chased them out with a whip while calling them thieves.
Jesus took a stand to deal with wicked men violently. That scares some Christians.
Some of them are good people, but naive.
Others are wolves themselves.
Joel Stiff's Adventure 
I was thinking about this just the other day. So many people accuse Christians of being unchristian because they are “judgmental.” Perhaps they rebuke a friend or family member or state their beliefs which are in opposition to the popular “world view.”
Jesus stepped on a lot of toes. He pointed out the misgivings of others. Spoke harshly. He did this in looking out for our best interest. Just as a parent disciplines a child. It was out of love. However, some believe that we, as Christians should be all love all the time; love meaning passive.
If we are to be like Jesus, we will stand up for right, resist those who are doing wrong, and not allow our beliefs or testimony to be tainted.
All this to say, Jesus didn’t flip tables because he was mean, he flipped them as an act of love. I just hope I don’t need to get loved quite like that.
Very true, Chris. Love does not equal passive. Love defends what is right. Thanks for reading!
