And what is the exceeding greatness of his power - On the language used here, compare the notes at 2 Corinthians 4:17. There is much emphasis and energy of expression here, as if the apostle were laboring under the greatness of his theme, and wanted words to express the magnitude of his conception. This is the “third” thing which he was particularly desirous they should know - that they should be fully acquainted with the “power” of God in the salvation of people. He refers not merely to the power which he had evinced in their salvation, but also to what the gospel was “able” to accomplish, and which they might yet experience. The “power” referred to here as exercised toward believers does not refer to one thing merely. It is the whole series of the acts of power toward Christians which results from the work of the Redeemer. There was power exerted in their conversion. There would be power exerted in keeping them. There would be power in raising them up from the dead, and exalting them with Christ to heaven. The religion which they professed was a religion of “power.” In all the forms and stages of it the power of God was manifested toward them, and would be until they reached their final inheritance.
To us-ward - Toward us, or in relation to us.
Who believe - Who are Christians.
According to the working of his mighty power - Margin, The might of his power. This should be taken with the clause in the following verse, “which he wrought in Christ;” and the meaning is, that the power which God has exerted in us is in accordance with the power which was shown in raising up the Lord Jesus. It was the proper result of that, and was power of a similar kind. The same power is requisite to convert a sinner which is demanded in raising the dead. Neither will be accomplished but by omnipotence (see the notes, Ephesians 2:5); and the apostle wished that they should be fully apprised of this fact, and of the vast “power” which God had put forth in raising them up from the death of sin. To illustrate this sentiment is one of his designs in the following verses; and, hence, he goes on to show that people before their conversion were “dead in trespasses and sins;” that they had no spiritual life; that they were the “children of wrath;” that they were raised up from their death in sin by the same power which raised the Lord Jesus from the grave, and that they were wholly saved by grace; Ephesians 2:1-10. In order to set this idea of the “power” which God had put forth in their regeneration in the strongest light, he goes into a magnificent description of the resurrection and exaltation of the Lord Jesus, and shows how that was connected with the renewing of Christians. God had set him over all things. He had put all things under his feet, and had made principalities and dominions everywhere subject to him. In this whole passage Ephesians 1:19-23; Ephesians 2:1-10, the main thing to be illustrated is the power which God has shown in renewing and saving his people; and the leading sentiment is, that the same power is evinced in that which was required to raise up the Lord Jesus from the dead, and to exalt him over the universe.
