A surefast way to keep catchphrases from becoming white noise is to continue to look at the truth revealed in Scripture. Paul has been encouraging the Philippians to persevere in faith, no matter what the circumstances look like around them. He is giving practical steps on how to live as a beloved community that lives out the kingdom of God in the here and now. To Paul, choosing joy is not always rainbows and butterflies, but can look like turning the other cheek, working hard, and standing firm.
