In the upper room just before His betrayal, the Lord Jesus prayed to His Father, remembering "the glory which I had with thee before the world was" (John 17:5). He had left heaven, however, when "the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth" (1:14). Then, when He miraculously turned water into wine at the wedding in Galilee, He "manifested forth his glory; and his disciples believed on him" (John 2:11).
In the days of His flesh, His glory was veiled, however, except in His life and words of grace and truth, and in His mighty works. He "made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross" (Philippians 2:7-8).
Finally, His glory seemed to be gone forever as He lay in a borrowed tomb. But then "God . . . raised him up from the dead, and gave him glory; that your faith and hope might be in God" (1 Peter 1:21).
He is now "the Lord of glory" (James 2:1), who, being the very "brightness of |God's| glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high" (Hebrews 1:3).
As He ascended back to heaven, all His hosts of angels welcomed their Lord of hosts with a mighty anthem of praise: "Lift up your heads, O ye gates; even lift them up, ye everlasting doors; and the King of glory shall come in. Who is this King of glory? The LORD of hosts, he is the King of glory" (Psalm 24:9-10). HMM http://www.icr.org/article/6821/
