¹² And may the Lord make your love for one another and for all people grow and overflow, just as our love for you overflows.

⁹ I pray that your love will overflow more and more, and that you will keep on growing in knowledge and understanding.

Loving One Another

⁷ Dear friends, let us continue to love one another, for love comes from God. Anyone who loves is a child of God and knows God. ⁸ But anyone who does not love does not know God, for God is love.

⁹ God showed how much he loved us by sending his one and only Son into the world so that we might have eternal life through him. ¹⁰ This is real love—not that we loved God, but that he loved us and sent his Son as a sacrifice to take away our sins.

¹¹ Dear friends, since God loved us that much, we surely ought to love each other. ¹² No one has ever seen God. But if we love each other, God lives in us, and his love is brought to full expression in us.

¹³ And God has given us his Spirit as proof that we live in him and he in us. ¹⁴ Furthermore, we have seen with our own eyes and now testify that the Father sent his Son to be the Savior of the world. ¹⁵ All who declare that Jesus is the Son of God have God living in them, and they live in God. ¹⁶ We know how much God loves us, and we have put our trust in his love.

God is love, and all who live in love live in God, and God lives in them.

³⁹ A second is equally important: ‘Love your neighbor as yourself.’^[a]

Love One Another

¹¹ This is the message you have heard from the beginning: We should love one another. ¹² We must not be like Cain, who belonged to the evil one and killed his brother. And why did he kill him? Because Cain had been doing what was evil, and his brother had been doing what was righteous. ¹³ So don’t be surprised, dear brothers and sisters,^[a] if the world hates you.

¹⁴ If we love our brothers and sisters who are believers,^[b] it proves that we have passed from death to life. But a person who has no love is still dead. ¹⁵ Anyone who hates another brother or sister^[c] is really a murderer at heart. And you know that murderers don’t have eternal life within them.

¹⁶ We know what real love is because Jesus gave up his life for us. So we also ought to give up our lives for our brothers and sisters. ¹⁷ If someone has enough money to live well and sees a brother or sister^[d] in need but shows no compassion—how can God’s love be in that person?

¹⁸ Dear children, let’s not merely say that we love each other; let us show the truth by our actions. ¹⁹ Our actions will show that we belong to the truth, so we will be confident when we stand before God.
