{3} Seeing then that we have such hope, we use great plainness of speech:

(3) He shows what this glory of the preaching of the Gospel consists in: that is, in that it sets forth plainly and evidently that which the Law showed darkly, for it sent those that heard it to be healed by Christ, who was to come, after it had wounded them.

People's New Testament

3:12 Seeing then that we have such hope. The blessed gospel hope.

We use great plainness of speech. With such a hope he has boldness to declare the gospel truths boldly and without reserve.

plainness of speech-openness; without reserve (2Co 2:17; 4:2).

Matthew Henry's Concise Commentary

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.
