The letter to the Philippians by Paul the apostle was written to say thanks for their monetary gift sent to him by Epaphroditus. He had gotten sick and almost died, so Paul is sending him back to the church at Philippi with this letter. The theme of this book is joy which comes from the all-sufficiency of Christ. Some popular sayings of Paul are in this letter such as, "He who began a good work in you will be faithful to complete it" (1:6) "For me to live is Christ and to die is gain" (1:21). "That at the name of Jesus every knee will bow, in heaven, in earth, and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father" (2:10-11). I press toward the mark for the prize of the high calling of God in Christ Jesus" (3:14). "Rejoice in the Lord, always, and again I say, rejoice" (4:4). "I can do all things through Christ who gives me strength" (4:13). "And my God will supply every need of yours according to his riches in glory in Christ Jesus" (4:19). Paul emphasized Christ's humility, believer's need for unity, worthy lifestyle, and contentment that comes in Christ.
