“But when one turns to the Lord, the veil is removed. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 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.” (2 Cor. 3:16-18).
Paul writes to the Corinthian church that we have confidence through Christ toward God (3:4), because the glory of the ministry of the Spirit whom Christ delivered us to is greater than the glory of the ministry of the Law (or the ministry of death). Not only that, but he says that the glory promised to believers (3:6) will far exceed the glory promised to those who try to work for forgiveness (3:7-11). And this is great news, because our minds were hardened (3:14) to the character of God in the Law; we put on a veil over our face and over our hearts, not because there isn’t any goodness in the Law, but because we didn’t want to behold God in it. Our sinfulness was more comfortable to us in our depravity than the glory of God.
“But when one turns to the Lord, the veil is removed.” A new Christian can truly see and behold the glory of the Lord (especially in the gospel)—for the first time, they have eyes and they can see because the veil is gone. “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.” God has removed the veil from our faces; he has removed our hardness of heart and our sinfulness that always runs to hide behind the veil; he has made us free from the bondage of our own will, and he has reformed our will to embrace that freedom; he is also transforming us into his image, and as we gaze upon him (especially in the gospel), we cannot help but be changed more and more.
