Ephesians 2:10 - Matthew Poole's English Annotations on the Holy Bible

For we, we believers, both Jews and Gentiles, are his workmanship; not only as men, but especially as saints, which is the proper meaning here. The Israelitish people formerly were God's work, Deuteronomy 32:6 Isaiah 43:21, Isaiah 44:21; so are believers under the gospel, being new creatures, Galatians 6:15. The apostle confirms what he said before, that by grace we are saved, and not of works, in that we are God's workmanship, and are formed by him ere we can do any good work; and his forming us in our regeneration is a part of the salvation mentioned Ephesians 2:8. Created in Christ Jesus; who, as our Head, enlivens us, as members united to him by faith. As the first creation was by Christ as the Second Person in the Trinity, 1 Thessalonians 1:3, so the second creation is by the same Christ as Mediator, the Lord and Head of the new creation, in whom we live, and move, and have our new being, and not in ourselves, 2 Corinthians 5:17. Unto good works: as the immediate end for which we are new-created. We receive our new being that we may bring forth new works, and have a carriage suitable to our new principle. Which God hath before ordained; or rather, as the margin, prepared, i.e. prepared and fitted us for them, by enlightening our minds to know his will, disposing and inclining our wills, purging our affections, &c. That we should walk in them; i.e. that we should glorify God in a holy conversation, agreeable to that Divine nature, whereof we are made partakers in our new creation.
