3:14 But their minds were blinded. So blinded that they cannot see to this day that it has been set aside by the New Covenant, and that its types, figures and shadows find their fulfillment in Christ.
Which [vail] is done away in Christ. Meyer, with many other able critics, contends that the proper translation of the latter part of the verse is: It not being disclosed that the Old Covenant is taken away in Christ. So also Conybeare and Howson. This is no doubt the meaning.
3:14 The same veil remaineth on their understanding unremoved - Not so much as folded back, (so the word implies,) so as to admit a little, glimmering light. On the public reading of the Old Testament - The veil is not now on the face of Moses or of his writings, but on the reading of them, and on the heart of them that believe not. Which is taken away in Christ - That is, from the heart of them that truly believe on him.
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.
