“He is the Son of God, and second person, and therefore the express image and brightness of His Father’s glory, (Hebrews 1:3) the essential substantial image of His Father, which transcends infinitely more all other drafts of Him than the image of a king in his son begotten like him, and in a board or tablet.
But this image, you will say, it is too bright for us to behold it shining in His strength, we being as unable to behold it in Him, as we were to see His Father Himself, who dwells in light inaccessible, which no eye can attain to.
Therefore that yet we may see it as nigh and as fully and to the utmost that creatures could; this Godhead dwells bodily in a human nature (Colossians 2:9), that so shining through the lantern of His flesh we might behold it.
His human nature and divine make up one person, and being so, are united together in the highest kind of union that God can be to a creature, and the nearest and fullest communications follow always upon the nearest union.
To Him therefore as man are communicated these riches of glory that are in the Godhead, as nearly and fully as was possible unto a creature; and being thus communicated, must needs shine forth in Him to us to the utmost that they ever could unto creatures.
And therefore more clearly than if millions of several worlds had been created every day on purpose to reveal God to us.
God having stamped upon His Son all His glory, that we might see the glory of God in the face of Jesus Christ, (2 Cor. 4:6).”
