love your enemies

That's what Jesus said.  He said many things that can change the world.  Theologians refer to this as the ethics of Jesus.  Jesus said it was the ethics of those who believed in Him.  He did promise to return.  He certainly came to lift the burden of sin and give us abundant life.  He also said "do good to them that despitefully use you and persecute you". (Matt 5:44).  In our own efforts it is a complete impossibility to accomplish this high ethic. Because of the work of Christ on the cross we can actually get it done!  Praise God!
