From Matthew Henry's Commentary:

"The apostle's design is to settle and establish the Ephesians in the truth, and further to acquaint them with the mystery of the gospel, in order to it. In the former part he represents the great privilege of the Ephesians, who, having been in time past idolatrous heathens, were now converted to Christianity and received into covenant with God, which he illustrates from a view of their deplorable state before their conversion (Ch. 1-3). In the latter part (which we have in the 4th, 5th, and 6th chapters) he instructs them in the principal duties of religion, both personal and relative, and exhorts and quickens them to the faithful discharge of them."
