10 In this the sons of God are manifest, and the sons of the devil: whosoever does not righteousness and that loves not his brother is not of God.
11 For this is the message that ye heard from the beginning, That we should love one another.
12 Not as Cain, who was of the wicked one and killed his brother. And why did he kill him? Because his own works were evil, and his brother’s righteous.
13 Marvel not, my brethren, if the world hates you.
14 We know that we are passed from death unto life, in that we love the brethren. He that does not love his brother abides in death.
15 Whosoever hates his brother is a murderer and ye know that no murderer has eternal life abiding in him.
16 In this we have known the charity of God because he laid down his life for us; we also ought to lay down our lives for the brethren.
