2 Corinthians 3:12-18; 2 Corinthians 4:1-2

12 Since, then, we have such a hope, we act with great boldness, 13 not like Moses, who put a veil over his face to keep the people of Israel from gazing at the end of the glory that was being set aside. 14 But their minds were hardened. Indeed, to this very day, when they hear the reading of the old covenant, that same veil is still there, since only in Christ is it set aside. 15 Indeed, to this very day whenever Moses is read, a veil lies over their minds; 16 but when one turns to the Lord, the veil is removed. 17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 18 And all of us, with unveiled faces, seeing the glory of the Lord as though reflected in a mirror, are being transformed into the same image from one degree of glory to another; for this comes from the Lord, the Spirit.
1 Therefore, since it is by God's mercy that we are engaged in this ministry, we do not lose heart. 2 We have renounced the shameful things that one hides; we refuse to practice cunning or to falsify God's word; but by the open statement of the truth we commend ourselves to the conscience of everyone in the sight of God.
