14Do everything without complaining or arguing 15so that you will be blameless and pure, children of God without any fault. But you are living with evil people all around you, who have lost their sense of what is right. Among those people you shine like lights in a dark world, 16and you offer them the teaching that gives life. So I can be proud of you when Christ comes again. You will show that my work was not wasted—that I ran in the race and won.
