One of the best-known Bible verses on the topic of joy is Philippians 4:4, “Rejoice in the Lord always; again I will say, Rejoice” (ESV). In a fallen world, it is easy to find excuses for being gloomy, but the apostle Paul wrote those words while a prisoner in Rome. In fact, despite his outwardly dreary circumstances, the whole letter to the Philippians is overflowing with joy and thankfulness. This hymn is a good reminder of the joy that Christians should display, regardless of circumstance.
