Avoiding "worldly" demands and customs is a long-standing passtime for Adventists and other protestant denominations. 

The lesson this week assumes this is the same as Paul's emphasis in Philippians 2 that we should "shine like bright lights in a world full of crooked and perverse people." We explore these verses, and they way they relate to living as agents of God's kingdom. Perhaps the focus on being different and increasingly set apart from the world is less helpful than a focus on being more similar to Christ.
