Paul uses the word "joy" to mean that the Philippian church is the cause of his happiness. A "crown" was made of leaves, and a man wore it on his head as a sign of honor after he won an important game. Here the word "crown" means the Philippian church brought honor to Paul before God. Alternate translation: "You give me joy because you have believed in Jesus, and you are my reward and honor for my work" (See: [[rc://en/ta/man/translate/figs-metonymy]])
