The first half of Paul’s letter to the Ephesians is the doctrinal part of the letter where the latter half is instruction on the way of righteousness. This is the same format Paul follows in all his letters - the first part being doctrinal, the latter being instruction in righteousness. In the first half, the doctrine he taught was God’s great plan with the earth and mankind and how the disciples had been called to be a part of his purpose. In the second half of the letter his instruction is to obey to “walk worthy of the vocation wherewith ye are called”.
Paul's letter to the disciples in Ephesus, a principal city of Asia Minor, gives a quiet exposition of the purpose of God in Christ and of the privileged position in that purpose to which the disciples had attained, even though they were Gentiles and not naturally God’s people.
