Filipenses 2

12 So then, my beloved, even as you have always obeyed, not only in my presence, but now much more in my absence, work out your own salvation with fear and trembling. 13 For it is God who works in you both to will and to work for his good pleasure.

14 Do all things without complaining and arguing, 15 that you may become blameless and harmless, children of God without defect in the middle of a crooked and perverse generation, amongst whom you are seen as lights in the world, 16 holding up the word of life, that I may have something to boast in the day of Christ that I didn’t run in vain nor labour in vain.
