12 So then, my dear ones, just as you have always obeyed [my instructions with enthusiasm], not only in my presence, but now much more in my absence, continue to work out your salvation [that is, cultivate it, bring it to full effect, actively pursue spiritual maturity] with awe-inspired fear and trembling [using serious caution and critical self-evaluation to avoid anything that might offend God or discredit the name of Christ]. 13 For it is [not your strength, but it is] God who is effectively at work in you, both to will and to work [that is, strengthening, energizing, and creating in you the longing and the ability to fulfill your purpose] for His good pleasure. 14 Do everything without murmuring or questioning [the providence of God], 15 so that you may prove yourselves to be blameless and guileless, innocent and uncontaminated, children of God without blemish in the midst of a [morally] crooked and [spiritually] perverted generation, among whom you are seen as bright lights [beacons shining out clearly] in the world [of darkness], 16 holding out and offering to everyone the word of life, so that in the day of Christ I will have reason to rejoice greatly because I did not run [my race] in vain nor labor without result. 17 But even if I am being poured out as a drink offering on the sacrifice and service of your faith [for preaching the message of salvation], still I rejoice and share my joy with you all. 18 You too, rejoice in the same way and share your joy with me.
