10In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother. 11For this is the message that ye heard from the beginning, that we should love one another. 12Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous. 13Marvel not, my brethren, if the world hate you.14We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. 15Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him. 16Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
