Paul writes the letter to the Philippian church while chained to guards in Rome. He reminds the Philippians how to find joy even in difficult circumstances. He will demonstrate that with the right definition of life (“to live is Christ”), any circumstance can be transformed by God into something meaningful. Like an alchemist turning lead to gold, God uses our trials both for His glory and our spiritual growth. Paul shows that true joy comes not from our circumstances, but from having Christ as our ultimate purpose and prize.
The book of Philippians is unique in that Paul’s words continually move back to being centered in joy. There is a constant in all of our seasons of life: Jesus reigns over created order and in this life, we will experience hardship. The way to walk in joy through all of our seasons of life is to have it centered in the constancy of knowing Jesus (Phil 2:6-8) who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. We know that every knee will bow and every tongue confess that Jesus is Lord (Phil 2:11).
