Adam Clarke's Commentary on the Bible

Verse 17 (Ephesians 1:17)

That the God of our Lord Jesus - Jesus Christ, as man and mediator, has the Father for his God and Father: and it is in reference to this that he himself says: I ascend unto my Father and your Father, and to my God and your God; John 20:17 .

The Father of glory - The author and giver of that glory which you expect at the end of your Christian race. This may be a Hebraism for glorious Father, but the former appears to be the best sense.

The Spirit of wisdom and revelation - I pray that God may give you his Holy Spirit, by whom his will is revealed to men, that he may teach and make you wise unto salvation, that you may continue to acknowledge him, Christ Jesus, as your only Lord and Savior.
