“That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him:”
King James Version (KJV)
1:17 That the Father of that infinite glory which shines in the face of Christ, from whom also we receive the glorious inheritance, #Eph 1:18|, may give you the Spirit of wisdom and revelation - The same who is the Spirit of promise is also, in the progress of the faithful, the Spirit of wisdom and revelation; making them wise unto salvation, and revealing to them the deep things of God. He is here speaking of that wisdom and revelation which are common to all real Christians.
Eph 1:17 That. This introduces the things for which he prayed God in their behalf. The Father of glory. The source of all spiritual glory. Give unto you the Spirit of wisdom. A gift of the Spirit. See PNT "1Co 12:8". Divine wisdom works wisdom in believers. And revelation in the knowledge of him. The Spirit that reveals a knowledge of God and spiritual mysteries. This Spirit would enable them to better comprehend the "mystery" of God, the divine plans for human redemption in a better knowledge of him.
