2 Cor.3:18 – 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.

This verse makes no sense to the natural, unrenewed mind. How could it? This verse is describing the work of the Holy Spirit on our lives, it is described as transformative. We are changed from the inside by gazing on the beauty of the Lord. Now this is something us Christians learn about as we grow older in the Lord. This verse describes beholding the Lord in the written word as well as soaking in His presence and experiencing the presence of the Lord on our whole being. These two disciplines bring us to a place where we can be literally changed from glory to glory. Here are two quotes, one from the Passion Notes followed by the Believer’s Bible Commentary.

Passion Notes

“The source of our transformation comes from Christ’s glory, and the destination we are brought to is more glory. The transforming glory is the result of gazing upon the beauty and splendor of Jesus Christ.”

“This marvelous, transforming process takes place from glory to glory, that is, from one degree of glory to another. It is not a matter of instant change. There is no experience in the Christian life that will reproduce His image in a moment. It is a process, not a crisis. It is not like the fading glory of the law, but an ever-increasing glory. The power for this wonderful process is the Holy Spirit of God—just as by the Spirit of the Lord. As we behold the Lord of glory, study Him, contemplate Him, gaze on Him adoringly, the Spirit of the Lord works in our life the marvelous miracle of increasing conformity to Christ.”

This is God’s ultimate plan, to display His glory in the lives of fallen human beings. It starts in this life but will be made complete in the life to come. We are not really sure what eternity will look like, what we do know is that Christ will be glorified throughout all eternity by the work He has done in each of us. The more we are changed into His image the more Christ is glorified. This is the point of glory to glory, to be transformed by the Spirit into the image of God’s Son.
