Of all the books in the Bible, Ephesians best encompasses all of Christian thought and life. It not only tells us of our blessings and position in Christ, but also guides us in our day to day living. Some of Paul's letters arose from specific circumstances; e.g., Colossians is written to correct doctrinal error. Ephesians seems to be a letter springing from Paul's desire that the believers should be fully grounded in the profound doctrines of the gospel and faithfully geared to live victorious lives for Christ. It is a guidebook for emotional, mental, relational and spiritual wellbeing.
