Rivalry?

Have you ever heard of inter-service rivalry? In a nation with large military forces there can be tension and competition between the different branches of service. They compete for funding and prominence. In time of war the top commanders try to overcome this to make the different branches function effectively together, for each has a part to play, and they are all ultimately on the same side. There are denominations within my church. Do you see rivalry between them? Yet I have given each a mission to carry out, and all who declare allegiance to me should recognize that they are on the same side with others who make the same profession. Realize that you are involved in a real war, and that you are more effective if you fight in coordination and cooperation with others who are on the same side.
