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] *2:13 God supports the believer, but it is the believer’s responsibility to do what he has been called by God to do.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.
