12 So then, my beloved, even as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling; 13 for it is God who worketh in you both to will and to work, for his good pleasure. 14 Do all things without murmurings and questionings: 15 that ye may become blameless and harmless, children of God without blemish in the midst of a crooked and perverse generation, among whom ye are seen as lights in the world, 16 holding forth the word of life; that I may have whereof to glory in the day of Christ, that I did not run in vain neither labor in vain.
