Learn more about Ephesians
Paul's letter to the Ephesians is different from his other letters. Writing it while in prison in Rome, it might have been intended to pass on to other towns like a 'round robin' as there is a space left in the address line to include somewhere else. He isn't writing to the Ephesians about any particular problem, instead he picks up a number of great Christian themes.
Ephesians is much prized because of this. The great preacher Spurgeon said we should 'read, mark, learn, and inwardly digest' this epistle. Paul writes about the new community which has been achieved by the work of Jesus through the Holy Spirit. We have been destined to be adopted as sons and daughters of God. Under Roman Law, when this was written, this would have been significant. Once adopted the child or adult was considered to be reborn and became a legitimate member of their new family. But Paul goes even further though, saying we are 'born' into this new Christian family.
Ephesians also has a brief greeting, unlike his other letters, just saying 'To the saints who are in Ephesus'. The word 'saints' simply means those Christians in Ephesus. We need to remember that Paul spent three years working in his great Greek city, and that it was here that he had taken the Christians away from the synagogue - a huge step towards the future.
