Jesus sent His disciples out in pairs to bring peace to their world. He implored them to bring it to all - not just some. Jesus was also a realist. Some will accept the offering of peace - and some will not. In this case, He said the peace will return to His followers! So giving of peace is always beneficial - even if it is not welcomed or received. We are called to bring peace to all regardless of its reception. Do we? It is our calling - we should.
