Mobs can be really scary because they lack the ability to think. It's all driven by energy. I think it's interesting to see not only Jesus reaction to his accusers, but how his accusers reacted. Caiaphas tries to freak out and act like none of this is a setup. I wonder how good of a job he did. At least he committed to the role by tearing his clothes.
Once people get all emotional and get a group all excited, it can be incredibly difficult to stop. If people start being negative, and then become vocal in their negativity, it can do the same thing to your ministry. I've seen it. I actually just went through a year of that with my middle school ministry. Now I've got lots of excitement on the bottom end and it already shows. JM
