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.
The message that we've heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And why did he kill him? Because his own works were evil, and his brother's were righteous. So marvel not, my brethren, if the world hates you ( 1 John 3:11-13 ).
