The Book of Ephesians, written by Paul, begins by establishing the spiritual blessings and divine adoption believers receive through Christ, emphasizing that salvation is a gift of grace, not earned by works. It highlights Christ's role in uniting both Gentiles and Jews into one body, the Church, and Paul's mission to reveal this mystery. The text then exhorts believers to live a life worthy of their calling, promoting unity, love, and righteous conduct by shedding their old sinful ways and embracing a new self in Christ. Finally, it provides guidance on various relationships within the household and concludes with an encouragement to stand firm against spiritual evil by donning the "armor of God."
