1:3–11 It was common for Graeco-Roman letters to include a thanksgiving section, but Paul’s language here goes beyond the customary expression of gratitude. Ever since Paul first preached the gospel at Philippi (Acts 16:11–40), the believers there had been among his strongest supporters (Phil 1:5). He thinks of them with warmth and affection (vv. 7–8) and prays that their love and wisdom will grow (v. 9).
