He constructed an offensive weapon and attacked the tables and goods of those who were selling in the Temple. The point was Jesus dove into conflict over an issue of right and wrong and the holiness of God's house. He was anything but peaceful. One of my Seminary professors pointed out the irony that people will easily get into arguments over such issues as what kinds of cars to buy but avoid discussing religion. One will argue that Fords are best and the other Buicks.
Farmers argue about the types of implements to use and their color.
People will argue about sports and politics. The irony here, as my professor pointed out, is that we argue about things that are of much less importance than religion. We argue about things which don't matter in eternity. You won't care if you are driving a Ford or Buick when you get to heaven or hell. What will be important is whether you get to heaven or hell.
