Ephesians 4:1

I therefore. This verse begins what may be called the practical section of the epistle, although the apostle Paul did not think of doctrine and practice as separate branches of the faith. Theory and application are interwoven in the texture of his presentation of the great theme of the unity of believers. But in this section special exhortations are given concerning Christian duties and privileges, in view of the grace that has been received and of the responsibilities that fellow believers have to one another. The stress is here placed on the effects rather than on the causes of spiritual living.

Prisoner. See on 3:1.

Walk worthy. See on Eph. 2:2 cf. Eph. 2:10; 5:8, 15; Col. 1:10. It is impossible to be entirely worthy of our calling, but one may be continually under the leading of God. God has not called us because we are worthy, for worthiness follows the call. No man would ever be called of God if it depended on his worthiness. When the prodigal son cried out that he was not worthy to be called his father’s son, he was expressing the conviction of all repentant sinners (Luke 15:19). The Ephesians, who were once aliens and foreigners, but who have now been united into one body with God’s formerly chosen people and have received of the promises, are called upon to exhibit certain visible evidences of that gracious change. To walk the Christian way means more than concern about separate acts of outward conduct; it relates to an inner condition and attitude that provides the motive force behind the acts.
