Love each other because God loved us
7 My friends, we should all love one another. It is God who makes us able to love other people. Everyone who loves other people has become a child of God. That person knows God. 8 Anyone who does not love other people does not know God. We know this because God's own nature is love. 9 This is how God showed that he loves us: He sent his only Son to come and live in the world. He did that so that we could have true life with God because we believe in Jesus. 10 This shows what real love really is: It is not that we have loved God, but that he loved us. He loved us so much that he sent his Son to save us from sin. He sent Jesus to die as a sacrifice to take the punishment for our sins.
11 My friends, this shows how much God has loved us. So then, we should all love one another.
12 Nobody has ever seen God. But, if we love each other, it shows that God really lives in us. Then we can love people completely, in the same way that God loves us. 13 God has given us his Holy Spirit to live in us. Because of this, we know that we are united with God. And we know that he is united with us. 14 God the Father sent his Son to come into the world. God sent him to save the people of the world from their sins. We apostles have seen that it is true, and now we are telling people about it.
15 If anyone says clearly that Jesus is the Son of God, that person is united with God. God is also united with that person. 16 We really know the kind of love that God has for us. We believe that God has put that love in us. God's nature is love. So, if someone continues to love other people, he is united with God. And God is united with him. 17 That is how we are able to love other people completely. Then, we will not be afraid on the day when God will judge all people. We can be sure that God will not punish us. We know this because we have lived in this world in the way that Jesus lived.
18 If we really love God, we will not be afraid of him. We cannot love him completely and also be afraid. We would only be afraid of God if we thought that he would punish us. So, if someone is afraid that God will punish them, it shows that they do not completely know God's love.
19 We are able to love God and other people because God loved us first. 20 Someone may say, ‘I love God.’ But if he says that and he hates other Christians, he is telling a lie. He can see other believers but he does not love them. So, he cannot love God that he has not seen. 21 This is the rule that God has given us. He has told us that anyone who loves him should also love other Christians.
4:21God's love is very special. Christians know how much God loves them. He sent Jesus to die on the cross to save us from our sin. We are no longer afraid that God will punish us for our sins. That is how much God loves us. Because of that, true Christians love other people. If they hate other people, it shows that they do not really know about God's love.
