I have always agreed with your sentiment here. The problem is, that most modern day christians that I know, teach this love, and practice this love, only amongst themselves, OR only as a tool to make you become ONE of them. They do not practice it simply because it is commanded. They practice it amongst themselves to appear more pious. Or they practice it toward others, only to "win souls" (a common term amongst them). Which Is why I could never go back to Christianity. Unfortunately, the modern practitioners of this religion, simply seem to be missing the boat, entirely.
