Whoever says he is in the light and hates his brother is still in darkness.

Whoever loves his brother abides in the light, and in him there is no cause for stumbling.

But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.

By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.

We should not be like Cain, who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother's righteous.

Do not be surprised, brothers, that the world hates you.

We know that we have passed out of death into life, because we love the brothers. Whoever does not love abides in death.

Everyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.

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

But if anyone has the world's goods and sees his brother in need, yet closes his heart against him, how does God's love abide in him?

If anyone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen.

And this commandment we have from him: whoever loves God must also love his brother.

If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that.
