Every Knee Shall Bow. Fear and Trembling? While imprisoned by Rome, the Apostle Paul wrote the revered book of Philippians. Although under house arrest and facing hardships and poverty, he was full of joy and gratitude. He continued to encourage his fellow servants, brothers and sisters living in a Roman colony called Philippi. In times of persecution, the Book of Philippians conveys powerful truth, messages and revelation for the whole Body of Messiah to hear and understand.
