Thanks to all who suggested possible sermon titles for Philippians 2:5-11. I've chosen "Gospel Glory" as the title of my sermon for Sunday. So, my friend Dan Rolfe is the winner of Filling Up the Afflictions of Christ.
I like both Gospel Humility and Gospel Exaltation. Both ideas are clearly in the text, but they both are in the text so to take one and not the other would only reflect half the text.
I also like Gospel Attitude and Gospel Minded, which reflect Paul's point nicely. The context of this passage is that we are to have the attitude of Christ.
But, in the end, I think Gospel Glory captures the big picture best. Christ's self-humbling and His super-exaltation were all for the glory of God the Father (v. 11).
