Ephesians is the church's great song of God's plan — Father, Son, and Spirit working from before the foundation of the world to gather one new people in Christ. Chapters 1–3 lay the doctrine, chapters 4–6 work out the life that flows from it, ending in the armor of God.
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God.”
“For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.”
“And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.”
“Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.”
