This commentary on Ephesians offers a somewhat different approach to its interpretation. God has a specific purpose in the believer's election, and the blessings he experiences as a result of believing are for a purpose. To fulfill this purpose, Paul, in chapters one through three, explains what the believer needs to know and in chapters four through six explains what he needs to do.
The emphasis is on God's eternal purpose and His plan for accomplishing it. Understanding His purpose and experiencing His blessings and equipping ought to be plenty of incentive in getting personally involved.
