Christ is the brightness of God's glory (Heb. 1:3). God's glory is incomparable with anything in creation.
"...the glory of the celestial is one, and the glory of the terrestrial is another. There is one glory of the sun, another glory of the moon, and another glory of the stars; for one star differs from another star in glory." (1Cor. 15:39)
Christ's glory far exceeds anything in creation. That Infinitely glorious one emptied Himself of holding on to that glorious form alone and took the form of man 2000 years ago.
"Though he was God, he did not think of equality with God as something to cling to. Instead, he gave up his divine privileges; he took the humble position of a slave and was born as a human being." (Phil. 2:6-7, NLT)
"So the Word became human and made his home among us. He was full of unfailing love and faithfulness. And we have seen his glory, the glory of the Father's one and only Son." (John 1:14)
And that's not all.
The glory of the Son shines in our hearts through the Gospel.
"For God, who said, "Let there be light in the darkness," has made this light shine in our hearts so we could know the glory of God that is seen in the face of Jesus Christ." (2Cor.4:6, NLT)
We are transformed into that same image as we read God's Word.
"But their minds were blinded. For until this day the same veil remains unlifted in the reading of the Old Testament, because the veil is taken away in Christ....
"But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord." (2Cor. 3:14,18)
And when He returns, He will transform our mortal bodies into the likeness of His glorious body.
"For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself." (Phil. 3:20,21)
We look towards that glory.
"The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs--heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together. For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. For the earnest expectation of the creation eagerly waits for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; because the creation itself also will be delivered from the bondage of corruption into the glorious liberty of the children of God." (Rom. 8:15-21)
