In Philippians 3:1–11, Paul writes about the gospel that saved him and produced in him true joy. He recalls his pre-conversion experience of striving for a works-based righteousness, and contrasts it with the joy-inspiring gospel of the free grace of God in Jesus Christ. If you want to know how Paul could maintain his joy while in a Roman dungeon, even as he prepared to send away his two closest companions (2:19–30), this text gives us the answer.
