Have you ever watched a movie where the man character was wronged and He/she goes after the bad guys and wipes out the entire family? You get a feeling of Justice has been served and no one will mess with that person again. It is a feel of satisfaction. Jesus is saying we need to look at life differently. Actually the OT speaks pretty clearly on how we are to act. “Do not seek revenge or bear a grudge against one of your people, but love your neighbor as yourself. I am the Lord” (Lev. 19:18). So Jesus points out to His disciples and all those listening that the interpretation and obedience to the Law has been lost. He is saying we are to be different. In what ways are we to be different?
