In Context

12 Not as Cain, who was of that wicked one, and slew his brother. And why slew he him? Because his own works were evil, and his brother's righteous.

13 Marvel not, my brothers, if the world hate you.

14 We know that we have passed from death to life, because we love the brothers. He that loves not his brother stays in death.

15 Whoever hates his brother is a murderer: and you know that no murderer has eternal life abiding in him.

16 Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brothers.

17 But whoever has this world's good, and sees his brother have need, and shuts up his bowels of compassion from him, how dwells the love of God in him?
