In Context

12 unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother's righteous.

13 Don't be surprised, my brothers, if the world hates you.

14 We know that we have passed out of death into life, because we love the brothers. He who doesn't love his brother remains in death.

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

16 By this we know love, because he laid down his life for us. And we ought to lay down our lives for the brothers.

17 But whoever has the world's goods, and sees his brother in need, and closes his heart of compassion against him, how does the love of God remain in him?
