v11 God has shown us how very kind he is. He has shown us that, because he came to *save all people. v12 And because God is so kind, he teaches us to do right things. We should stop doing bad things that do not make God happy. We should stop wanting strongly the things that belong to this world. Instead, God teaches us to rule ourselves properly. He teaches us to do what is right. He teaches us to do the things that make him happy. We should do these good things while we live in this world.
v13 We should do these good things while we wait for Jesus to return. This is our hope that makes us happy. On that good day, Jesus will certainly show everyone how very great he is. Jesus Christ is our great God and *Saviour. v14 He gave himself for us. So he made us free from every bad thing, so that we could be completely good and clean inside ourselves. So then, we could become his own special people, who really want to do good things.
v15 You should teach these things, with all authority. Tell the Christians strongly the things that they must do. Tell them the things that they must not do. Do not let anyone think that they know better than you.
