This introduction to Paul's letter to the Philippians will reveal some very interesting history about this city. But underneath that history we see that Paul may have revealed a theme for his letter. Paul's love for the believers in Philippi and his encouragement for them in the midst of their persecution shows us that Paul wanted them to know what real joy is. Joy, not happiness, joy, not health, wealth or prosperity, but real joy. Joy that grows out of God's favor and grace for us, His people.
