1 John 3:10-20

10 In this the children of God are revealed, and the children of the devil. Whoever doesn't do righteousness is not of God, neither is he who doesn't love his brother.

11 For this is the message which you heard from the beginning, that we should love one another;

12 unlike Kayin, 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. 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 shuts up his compassion from him, how does the love of God remain in him?

18 My little children, let's not love in word only, neither with the tongue only, but in deed and truth.

19 And by this we know that we are of the truth, and persuade our hearts before him,

20 because if our heart condemns us, God is greater than our heart, and knows all things.
