Unity through revelation
God works in our prayers
God works in us through the Trinity
God send the Son so that the Spirit may give us knowledge of Him
The defining point of Paul’s prayer: Is that they “may know”
The hope of God’s calling
He called us to Christ and holiness, to freedom and peace, to suffering and glory. More simply, it was a call to an altogether new life in which we know, love, obey and serve Christ, enjoy fellowship with him and with each other, and look beyond our present suffering to the glory which will one day be revealed. This is the hope to which he has called you
The wealth of His inheritance
This inheritance is his and yet its benefits for us come graciously from him as we share in it. The verse alludes to having awareness of this whole package. This is God’s inheritance because his people are his possession and they are the beneficiaries of that relationship. It is an honour to belong to God and to receive what he gives as a result. This is where the core of a stable personal identity in Christ comes from: we belong to the Creator God and are precious to him. This idea is applied to Gentiles in 2:11–22 and looks back to a degree to verse 7.
the calling we have is not in this case what we inherit but that which God inherits in us. God considers us a treasure (riches)! That to which we are called and on which we are to set our hope is not selfish gain but God’s good, which is to the praise of his glory (vv. 6, 12, 14). When Paul tell us in 4:1 to live worthily of “the calling [we] have received,” he probably has in mind not so much the work we are called to do or the blessing we are called to receive in heaven, but the share we are to have in bringing glory to God.
Greatness of His power
He writes not only of God’s ‘power’, but also of ‘the energy of the might of his strength’ (a literal rendering of the working of his great might, verse 19), and he prays that we may know the greatness of it, indeed the immeasurable greatness of it in (better ‘for’ or ‘towards’) us who believe.
We know this power is real because of the work that the Father did in Jesus. He gives us three examples:
Jesus resurrection and ascension
Jesus authority over evil
Jesus headship over the church
Pointing out that the ‘body’ and the ‘fullness’ images come together in Ephesians 4:13–16 and Colossians 1:18–19 as well as here, and that medical writers of approximately Paul’s time, like Hippocrates and Galen, thought of the head or brain as controlling and coordinating the functions of the body, Dr Barth summarizes Paul’s understanding that ‘the head fills the body with powers of movement and perception, and thereby inspires the whole body with life and direction’.
