Ephesians 4:1-6
Unity in the Body of Christ
July 25, 2027

Overview & Insights
“There is one body and one Spirit… one Lord, one faith, one baptism.” (Ephesians 4:4–5)
Chapter 4 begins what often is referred to as the ethical or practical section of the epistle. If chapters 1–3 provide the theological basis for Christian unity, then chapters 4–6 contain the practical instruction for its maintenance. Unity has been established (the indicative); now it becomes the duty of the believers to strengthen and maintain unity in their fellowship (the imperative).
