What's Different About This Church?

Henrietta Mears, in her classic work What the Bible Is All About, points out that this is Paul's most joyful epistle.

In his other letters to specific churches, Paul has sharper and more specific criticisms. But the church at Philippi does not receive this kind of negative feedback.

What was it about this church? How did they receive Paul's godly approval? What was different about this congregation?

Internal evidence may not be enough to answer this question. It may take most of the remaining 8 years, 7 months of my nine-year journey to puzzle out an answer to this question.
