Having the glory of God,.... Not only upon their souls, which will lie in the glorious robe of Christ's righteousness, the bride's wedding garment being on them, in the perfect holiness which will be in them, and in that complete knowledge of all spiritual and heavenly things they will be possessed of, they will have a glory revealed in them; but upon their bodies also...

Albert Barnes Presbyterian @notesbybarnes
