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.

16. Moses took off the veil on entering into the presence of the Lord. So as to the Israelites whom Moses represents, "whensoever their heart (it) turns (not as English Version, 'shall turn') to the Lord, the veil is (by the very fact; not as English Version, 'shall be') taken away." Ex 34:34 is the allusion; not Ex 34:30, 31, as Alford thinks. Whenever the Israelites turn to the Lord, who is the Spirit of the law, the veil is taken off their hearts in the presence of the Lord: as the literal veil was taken off by Moses in going before God: no longer resting on the dead letter, the veil, they by the Spirit commune with God and with the inner spirit of the Mosaic covenant (which answers to the glory of Moses' face unveiled in God's presence).
