"Do everything without complaining or arguing, so that you may become blameless and pure, children of God without fault in a crooked and depraved generation, in which you shine like stars in the universe, as you hold out the word of life- in order that I may boast on the day of Christ that I did not run or labor for nothing."
Further instructions from Paul on how to live each day. I just love Philippians- it's soaked with commands of how to live a Christ-centered life and "work out your salvation". What I love about this chapter is that Paul talks about humility in the previous verses and then uses Christ as the pinnacle example of humility. He then writes of the glory of Christ and that we are to confess that Jesus is Lord and bow before him. Then Paul says "Therefore". Because of what Christ has done in humility and because of the glory of who He is, "continue to work out your salvation!" I love it- choice of words and everything. Salvation IS a one-time deal but it needs to be continually worked out in response to the gospel! What a seemingly paradoxical conclusion- but it's how we are to live!
So then, further instruction on how to work out salvation. Being joyful always! Do NOTHING while complaining. We're working for God- how could we grumble or bicker?! When you complain, people notice. It's not an amiable or attractive quality to have. We're called to shine like STARS in this universe. That's bright. We're not flashlights or fireflies that shine pretty bright but turn off after a little bit. We're STARS that never are to burn out or turn off. And the Holy Spirit sustains that light as we "hold out the word of life".
[Tangent] The Bible is the word of life- it's not a book about how you can be a better person; it's not a self-help book. It's a book about GOD, the story of redemption, bringing all the glory to Him. So we must read the Bible to know more of who God is and not go into it thinking, "Oh, David and Goliath- that's a story about how I can defeat things in my life." NO- that's a story that points to Christ because Christ is the greater David that defeated sin! (these are concepts I've taken from sermons of Matt Chandler and John Piper)
But the point is, we must CLING to the 'word of life' and be willing to SUFFER for it as Paul did. No one can separate us from the love of God. So, with that hope and security, we can have confidence in suffering to illuminate the gospel and glorify God.
