"Cooperate"? You mean, if people would just:
--love their neighbors the same way they love themselves?
--consider others to be their family?
--not steal, or kill, or lie, or covet, or cheat?
--were tolerant of ideas they didn't invent themselves? Were willing to accept that not everyone thinks the same things they do, and to not excoriate and pillory them for not being politically correct? To not threaten to kill or punch people they don't agree with?
I don't think that's what those guys meant, but it's the truth: if we would just follow the teachings of Jesus Christ, just think of what we could accomplish!
