Read Matthew 21:12-17.Who ever said that Christians should be mamby-pamby whimps. Our Lord certainly wasn't. In fact, He'd plain and simply had had it with the hypocrites. And He backed it all up with Scripture. Did you notice that is basically all He says. No debate, no arguing, no insults or sarcasm -- just the Word of God.
"Jesus entered the temple area and drove out all who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves." NIV
I really don't have much more to say. This Scripture passage completely speaks for itself. I'll just add one instructional note: We must know the Word and character of God to speak His Scripture in truth and love. So I guess I'd better study some more.
