Mike Riccardi recently posted a great article at The Cripplegate on the book of Philippians. He shows how studying theology and growing in virtue are inseparable.
Although Riccardi’s point is well-made, I commend his article to you more for his excellent model of Bible study. He identifies the main point of Philippians, and he traces out Paul’s flow of thought effortlessly.
The Book of Philippians is about the Gospel. It’s not quite an exposition of the doctrinal content of the Gospel, like Romans is. And it’s not quite a defense of the Gospel in the face of heresy, like Galatians is. Philippians is more about the implications the Gospel has on the various aspects of our lives as believers. It’s about how we are to live in light of the Gospel. The thesis verse of the letter is Philippians 1:27, in which Paul commands his dear friends to “conduct yourselves in a manner worthy of the Gospel of Christ.”
