3:18 {5} But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, [even] as by the Spirit of the Lord.
(5) Continuing in the allegory of the covering, he compares the Gospel to a glass, which although it is most bright and sparkling, yet it does not dazzle their eyes who look in it, as the Law does, but instead transforms them with its beams, so that they also are partakers of the glory and shining of it, to enlighten others: as Christ said unto his own, You are the light of the world, whereas he himself alone is the light. We are also commanded in another place to shine as candles before the world, because we are partakers of God's Spirit. But Paul speaks here properly of the ministers of the Gospel, as it appears both by that which goes before, and that which comes after, and in that he sets before them his own example and that of his fellows.
3:18 But we all. All Christians.
With open face beholding as in a mirror the glory of the Lord. Looking to Jesus and beholding in his covenant, in our hearts and minds as in a mirror, and contemplating his glory.
Are changed into the same image. To look to Jesus has a transforming power. If we gaze upon him, we will become like him. As Moses unveiled before the Lord shone with the glory of the Lord, so we shall reflect the glory of Christ, and show forth his likeness.
From glory to glory. Developing from one stage of glory to a higher one.
[Even as by the Spirit of the Lord. Rather, The Lord the Spirit, as in the Revised Version. 2Co 3:17 declares the Lord is that Spirit. Our glory is from the Lord the Spirit. The figure here is a very beautiful one. By gazing upon the Lord we become like him and show forth his glory.
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.
3:12-18 It is the duty of the ministers of the gospel to use great plainness, or clearness, of speech. The Old Testament believers had only cloudy and passing glimpses of that glorious Saviour, and unbelievers looked no further than to the outward institution. But the great precepts of the gospel, believe, love, obey, are truths stated as clearly as possible. And the whole doctrine of Christ crucified, is made as plain as human language can make it. Those who lived under the law, had a veil upon their hearts. This veil is taken away by the doctrines of the Bible about Christ. When any person is converted to God, then the veil of ignorance is taken away. The condition of those who enjoy and believe the gospel is happy, for the heart is set at liberty to run the ways of God's commandments. They have light, and with open face they behold the glory of the Lord. Christians should prize and improve these privileges. We should not rest contented without knowing the transforming power of the gospel, by the working of the Spirit, bringing us to seek to be like the temper and tendency of the glorious gospel of our Lord and Saviour Jesus Christ, and into union with Him. We behold Christ, as in the glass of his word; and as the reflection from a mirror causes the face to shine, the faces of Christians shine also.
