Philippians 2:14-15 AMP:
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],
