Summary: There's an old song that goes, "...and they'll know we are Christians by our love." Notice how it doesn't say "by our clothes", or "by our cars", or "by our careers/cash worth/college degrees"! The world will know we love God when they see us loving <strong>each other</strong> -- even those we don't necessarily get along with or like. When we love one another we demonstrate to the world the love God has for them -- and we're able to love them because He first loved us.
