Paul’s letter to the Ephesian Christians is centred around the great truth of believers being one Body in Christ. Christ is the Head of the church, and the church is His Body (Eph. 1:22,23). Each believer is a member of this Body. The first half of the letter to the Ephesians deals with the doctrine of the Body of Christ. The second half of the letter deals with the practical outworking of this truth. And this is how the second half begins: “Therefore….. walk in a manner worthy of the calling with which you have been called, with all humility and gentleness, with patience, showing forbearance to one another in love, being diligent to preserve the unity of the Spirit in the bond of peace…..(for we are all parts of) one body” (Eph. 4:1-4). In other words, once a person has understood and “seen” this truth of the church being the Body of Christ, he should long to walk in humility, gentleness, patience, forbearance, love, unity and peace with his fellow-believers. When a Christian does not walk like that, it indicates that he hasn’t seen the Body of Christ.
