Ephesians 1:6

To the praise of the glory of his grace
The grace of God manifestly appears in the predestination of men to adoption; in that God had no need of sons, he having a dear and well beloved one; in whom he is well pleased; and in that those he adopts are so unworthy of the relation; and in that men, and not angels, should be taken by him into his family; and that some, and not others of the same race; and that this should be before the world was; and in providing Christ as a Redeemer, to open the way for the reception of this grace and happiness; and in appointing the grace of faith to be the receiver of it: and the glory of the grace of God appears herein; the glory of God is the supreme end of all he does; and the glory of his grace, and not his power, or other perfections of his, and the manifestative glory of that is here intended; yea, the "praise" of that glory: and this end is answered, when the children of God ascribe their adoption to the free grace of God; and when they admire it, and are thankful for it, and walk worthy of the relation they are brought into:

wherein he hath made us accepted in the beloved;
the Vulgate Latin and Ethiopic versions read, "his own beloved Son", and so the Claromontane exemplar; the Lord Jesus Christ, who is the beloved of God the Father; and was so from everlasting, and will be so to everlasting; which has appeared by his nearness to him, lying in his bosom; by his being privy to all his counsels, purposes, and designs; in putting all things into his hands, and in showing him all that he does; and by his giving him honour and glory, as man and Mediator: and he is the beloved of the saints, for the transcendent excellencies that are in him, and for his love to them, and for what he has done for them, and is unto them; and in him is their acceptance: which is to be understood of the acceptance of their persons, as founded in the blood and righteousness of Christ, and so of their services in him; of God's act of delight and complacency in them, as considered in Christ; who looks upon them, and is well pleased with them, and rests in his love towards them; which is an amazing instance of grace: it was grace that gave them a being in Christ, and which has provided in predestination everything to make them grateful to God; and the very act of acceptance is of mere grace; for internal grace, or grace infused, is not here meant, but the free favour of God: some read not "in which", but "which" (ecaritwsen) , "he freely gave us in the beloved"; so the Alexandrian copy, and some others, and the Syriac and Arabic versions.
