But whatever gain I had, I counted as loss for the sake of Christ. 8 Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ —Philippians 3:7-8
One reason Jesus is so glorious is simply because everything that is is because of him. He is the uncreated one to whom we owe all praise and worship and honor.
In his book, Seeing and Savoring Jesus Christ, John Piper explains:
The first particular glory that upholds all the rest is the mere eternal existence of Christ.
If we will simply ponder this as we ought, a great ballast will come into the tipping ship of our soul. Sheer existence is, perhaps, the greatest mystery of all. Ponder the absoluteness of reality. There had to be something that never came into being. Back, back, back we peer into endless ages, yet there never was nothing. Someone has the honor of being there first and always. He never became or developed. He simply was. To whom belongs this singular, absolute glory? The answer is Christ, the person whom the world knows as Jesus of Nazareth. . . .
Jesus Christ is the Creator of the universe. Jesus Christ is the Alpha and Omega, the first and the last. Jesus Christ, the Person, never had a beginning. He is absolute Reality. He has the unparalleled honor and unique glory of being there first and always. He never came into being. He was eternally begotten.
The Father has eternally enjoyed “the radiance of the glory of God and the exact imprint of his nature” (Hebrews 1:3) in the Person of his Son. Seeing and savoring this glory is the goal of our salvation. “Father, I desire that they also, whom you have given me, be with me where I am, to see my glory that you have given me” (John 17:24). To feast on this forever is the aim of our being created and our being redeemed.
