12 My dear people, you have always obeyed me. God has saved you from wrong ways. Now show this by the good things that you do. You must live that way, not only when I am with you, but much more now that I am not with you. Think of how wrong it will be if you do not. Try hard to work out how to do it.
13 For God is at work in you. He helps you want to do it. And he helps you do what he wants you to do.
14 Do everything without grumbling or making trouble.
15 In that way you will be completely good. No one will be able to say anything wrong about you. You will be Gods good children living amongst bad people. Among them you will shine like lights in the world.
16 You will have the message of life for them. I will be proud of you when Christ comes. My work and trouble will not be for nothing.
