2 Corinthians 3:18 And, accordingly, all we that believe in him, beholding as in a glass - In the mirror of the gospel. The glory of the Lord - His glorious love. Are transformed into the same image - Into the same love. From one degree of this glory to another, in a manner worthy of his almighty Spirit. What a beautiful contrast is here! Moses saw the glory of the Lord, and it rendered his face so bright, that he covered it with a veil; Israel not being able to bear the reflected light. We behold his glory in the glass of his word, and our faces shine too; yet we veil them not, but diffuse the lustre which is continually increasing, as we fix the eye of our mind more and more steadfastly on his glory displayed in the gospel.
In the practical sense, what it means is from one growth to the next. We come to Jesus as a child with wonder and question. He brings answers through His Word, (Bible), but He also works it out in our daily life as we learn. At some point, that is settled within us and is active in our life and becomes who we are in that area. But, as this is happening, we are also learning more, growing in God, so to speak. This is a continuing process throughout our life and we grow from glory to glory. We have begun to learn how Jesus thinks and who He is and through this time and with prayer and a daily walk with Him, we come from glory to glory, seeing more in the way that He sees, having our desires become more like his desires as we grow and we and our lives are changing progressively. This continues throughout our life and it would automatically glorify Him and His Ways, and not our old selfish nature.
