In the building of a spiritual family the work of the Holy Spirit is the vital power. Here several Holy Spirit verses in Ephesians are explored (including 'Be filled with the Spirit') to show the different activities of the Spirit in the Christian life.

Paul's special calling to unfold to the Gentile world the hitherto unproclaimed grace of God, person of Christ, and oneness of saved Gentiles with saved Jews in one body. Here also are the unsearchable riches of Christ, and the ultimate purpose of the Gospel.

The apostle prays that believers will have Christ in their hearts (here explained), and rooted and grounded in love for Him, we will know more of His for us. Here is the scope of the breadth, length, depth and height of that love.

The true church is a demonstration to the world of God's glory. Human nature prefers to vaunt personalities, preachers, even musicians and their produce, but our God-given role is to show the fruits of the converting and sanctifying work within us. 

Beginning with prerequisites for Christian fellowship, Paul presents seven reasons for close union within churches, each a powerful encouragement. What it means to be one body, under one Holy Spirit, with one eternal hope, one Lord, one faith, one baptism, and one Father.

First, the nature of God's calling - irresistible and transformational, also the basis of assurance; second, the objective of the call - pardon, liberty, holiness and heaven; third, the character of the called - lowliness, meekness, patience, and forbearance among believers and before the world.

The apostle first shows that the ministry of Christ's church is described in prophecy. He then identifies the different kinds of teacher by their tasks (expounded here), and states the great objectives of all ministry - soul-winning, sanctification, and closeness to Christ.
