Though it may sound like a simple introduction, Paul's prologue (Ephesians 1:1-2) sets the foundation for the entire book of Ephesians. He declares that he is an apostle of Jesus Christ by God's will and that he is writing to the saints (holy set-apart ones who have the life of Christ within) and believers in Ephesus. In this expositional Bible study, we examine the keywords of this passage and show how Paul is arguing that our entire lives would be wrapped up and defined by Jesus Christ.
