What does Philippians 3:1 mean?

This verse marks a transition from the first half of Paul's letter to a new section. Paul notes the shift by explicitly referring to rejoicing. Despite the struggles both he and the church faced, they were to have joy in God. "Rejoice" is a theme repeated nine times in this letter, seen in Philippians 1:18 (twice); 2:17, 18, 28; 3:1; 4:4 (twice), and 10. To rejoice is often associated with both community and with rejoicing in the Lord. This is part of Paul's continued emphasis on the mind-set, or the attitude, of a Christian believer.

Based on this verse, it seems likely Paul had taught the Philippians about rejoicing in the past. This may also be a reference to the instructions he is about to give, involving false teachers. Coaches and mentors often note that repetition is a key to getting a message across. For Paul to remind the Philippians about rejoicing was nothing difficult for him. And, the reminder was certainly beneficial for them. Given Paul's present circumstances it was particularly easy for him to include this as part of his message, at least in writing. That a man imprisoned for the sake of Christ is reminding free people to "rejoice" is also striking.
