From the back:
"It is easy to rejoice when things go well. But Paul wrote "Rejoice in the Lord always" when he was in prison. He experienced a joy that was not dependent on circumstances, a contentment that difficulties could not suppress. In his brief letter to the Philippians, Paul teaches us how to live joyfully in the midst of troubles by focusing our attention on the One who is over every situation."
