Chapter 4 marks a change in Ephesians. Chapters 1-3 were focused primarily on doctrine, but now the focus changes to duty. We must be careful not to forget the great truths of chapters 1-3, for in them is the knowledge and power we need to live as believers. In our current passage, The apostle Paul urges believers to conduct their lives in a manner that is in keeping with the great blessings ;aid out in chapters 1-3 (being “in Christ,” being chosen, redeemed, forgiven, adopted, rescued, etc.). This will take four attitudes that our Savior also exhibited, humility, meekness, patience and forbearance – without which we cannot either maintain unity or purity (the basic themes of chapters 4-6). In verse 3 Paul tells us that the first goal of walking worthy and of these attitudes is to be eager to maintain the unity of the Spirit through the bond of peace. This peace, which Christ has established, becomes the means through which unity is maintained, and so the peace of the Church must be sought out and fought for.
