Behold, how great a love the Father has bestowed on us, that we should be called children of God! For this cause the world doesn't know us, because it didn't know him.
Pretty powerful words. It should cause us to examine our own lives. If I am living a life of practicing sin, I really don't know Him. I really haven't seen Him. If I really know Him, then I'm gonna be free from the practice of sin.
