¹¹ For this is the message which you heard from the beginning, that we should love one another; ¹² unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his deeds 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, then closes his heart of compassion against him, how does God’s love remain in him? ¹⁸ My little children, let’s not love in word only, or 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. ²¹ Beloved, if our hearts don’t condemn us, we have boldness toward God; ²² so whatever we ask, we receive from him, because we keep his commandments and do the things that are pleasing in his sight. ²³ This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded. ²⁴ He who keeps his commandments remains in him, and he in him. By this we know that he remains in us, by the Spirit which he gave us.

⁷ Beloved, let’s love one another, for love is of God; and everyone who loves has been born of God, and knows God. ⁸ He who doesn’t love doesn’t know God, for God is love. ⁹ By this God’s love was revealed in us, that God has sent his one and only Son into the world that we might live through him. ¹⁰ In this is love, not that we loved God, but that he loved us, and sent his Son as the atoning sacrifice^[a] for our sins. ¹¹ Beloved, if God loved us in this way, we also ought to love one another. ¹² No one has seen God at any time. If we love one another, God remains in us, and his love has been perfected in us.

¹³ By this we know that we remain in him and he in us, because he has given us of his Spirit. ¹⁴ We have seen and testify that the Father has sent the Son as the Savior of the world. ¹⁵ Whoever confesses that Jesus is the Son of God, God remains in him, and he in God. ¹⁶ We know and have believed the love which God has for us. God is love, and he who remains in love remains in God, and God remains in him. ¹⁷ In this, love has been made perfect among us, that we may have boldness in the day of judgment, because as he is, even so we are in this world. ¹⁸ There is no fear in love; but perfect love casts out fear, because fear has punishment. He who fears is not made perfect in love. ¹⁹ We love him, because he first loved us. ²⁰ If a man says, “I love God,” and hates his brother, he is a liar; for he who doesn’t love his brother whom he has seen, how can he love God whom he has not seen? ²¹ This commandment we have from him, that he who loves God should also love his brother.
