The Temple would have been no place for someone who didn’t like the sight of blood. The whole place must have been covered in it. This seems really gory, but God didn’t put this in place for no reason. It also wasn’t in place to satisfy some blood lust of the Almighty. It was to bring the people to repentance, and their repentance was dire business. Is there any thing more significant than the loss of a life? God didn’t think so, and that’s why Jesus made that very sacrifice.
