Philippians 2:15

Textus Receptus:
ινα γενησθε αμεμπτοι και ακεραιοι τεκνα θεου αμωμητα εν μεσω γενεας σκολιας και διεστραμμενης εν οις φαινεσθε ως φωστηρες εν κοσμω

King James:
That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;

Comments:
blameless: Of course, being blameless does not imply not being blamed, only not giving cause for being blamed. Peter recognizes this distinction and makes a significant point of it in 1 Peter 2:20. Paul uses the same word for "blameless" in chapter 3:6.

harmless: This word is translated as "simple" in the King James in Romans 16:19 because what Paul means by being harmless is being without ulterior motive--not mixed in purpose but pure.

sons of God: This use of this phrase makes the meaning of passages like Matthew 5:45 clearer. His point is not that they do something in order to become children of God, but in order that they act like God would act and therefore fill the role of the inheritors of the kingdom.

nation...ye shine: Paul assumes that the world around believers will be corrupt, and that the role of Christians in that world will always be to shine as lights in darkness. In other words, sin will continue in the world. Persecution will continue in the world. Christians will not usher in the kingdom. Christians will stand in opposition to the world. That fact is not a limitation on the impact of Christians on the lives of the lost but a context in which Christian faithfulness will be best defined and most needed. Jesus teaches about the same context in John 15:18-19.

crooked and perverse: "Crooked" emphasizes the wrong bent of their own nature. "Perverse" points to something that has happened to them--that they have been turned aside from the good to evil. The same two elements are present in James' description of temptation in James 1:14.

Expanded Paraphrase:
The result of thinking like Christ--of learning to put others first and of acting without the dissatisfaction that brings strife--will be that you take away every real justification for being condemned, that you have integrity in everything you do with no ulterior motives to create suspicion. You really will be like Jesus, representing your Father in this world. And the world needs it. You will be shining like lights in a world filled with darkness, with people who are not pointed in the right direction and have been thoroughly turned against everything good and right.
