Verses 12-14 always reminds me of the responsive obedience that God requires of those of us whom He has welcomed into His family.
He has shown you, O mortal, what is good. And what does the Lord require of you? To act justly and to love mercy and to walk humbly with your God. (Micah 6:8, NIV)

What I’m getting at, friends, is that you should simply keep on doing what you’ve done from the beginning. When I was living among you, you lived in responsive obedience. Now that I’m separated from you, keep it up. Better yet, redouble your efforts. Be energetic in your life of salvation, reverent and sensitive before God. That energy is God’s energy, an energy deep within you, God himself willing and working at what will give him the most pleasure.
Do everything readily and cheerfully—no bickering, no second-guessing allowed! Go out into the world uncorrupted, a breath of fresh air in this squalid and polluted society. Provide people with a glimpse of good living and of the living God. Carry the light-giving Message into the night so I’ll have good cause to be proud of you on the day that Christ returns. You’ll be living proof that I didn’t go to all this work for nothing.
Philippians 2:12-16, The Message
