2Cor. 3:18 And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.
Salvation is an amazing thing. It is not based on our efforts but is entirely dependent on supernatural revelation. That is especially hard in our secular world, everything is so predictable and dependent on human talent and human effort. Something supernatural makes humans really uncomfortable because it places us in a place of total weakness and total dependency on something way out of our control. That “something” is the Lord and that thing that He does is a total work of grace. Unexplainable light begins to shine into our hearts from hearing or reading the Word of God. We become aware of our sinfulness, His mercy, and His power to change our lives. Like today’s verse says, we are transformed, totally and absolutely recreated into different kinds of people. The work of God is thorough, our very nature is different. Here is how John Piper describes it.
“This new birth, “through the living and abiding word of God” (1 Pet. 1:23), gives the light of the knowledge of the glory of God. “God, who said, ‘Let light shine out of darkness,’ has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ” (2 Cor. 4:6). This supernaturally given, spiritual sight of the glory of God in Christ is the ground of saving faith. God is seen with the eyes of the heart as truly as the eyes of our head see the sun in the sky. And this sight of the glory of God in Christ compels us. It is no more resistible than the enjoyment of your favorite food is resistible when it is in your mouth. And so it is when God becomes your favorite, by the opening of your eyes to see his convincing and enthralling beauty. To see him as supreme in beauty is to desire him above all.”
There is a suddenness as well as a long slow effect of this life change. For many, there is a dramatic life change almost instantaneously. For those who continue in His word, the supernatural change happens the rest of their lives. We are being changed from one degree of glory to another.
