Imagine sitting down to write a letter to a group of friends you haven’t seen for a long time. These are people that stood by your side, people you love dearly. That is the type of letter the apostle Paul writes to a group of Jesus followers in the ancient city of Philippi. Joy fills his heart as he remembers what they share together. Affection fills his prayers as he asks for their love to grow and overflow. What did they share that brought so much joy? What did they need that only love could answer?
