4 Rejoice in the Lord always. I will say it again: Rejoice!
“It seems strange that a man in prison would be telling a church to rejoice. But Paul’s attitude teaches us an important lesson: Our inner attitudes do not have to reflect our outward circumstances. Paul was full of joy because he knew that no matter what happened to him, Jesus Christ was with him. Several times in this letter, Paul urged the Philippians to be joyful, probably because they needed to hear this. It’s easy to get discouraged about unpleasant circumstances or to take unimportant events too seriously. If you haven’t been joyful lately, you may not be looking at life from the right perspective.” (Life Application Study Bible 1998)
