2 Corinthians 3:12-18

Seeing then that we have such hope, we use great plainness of speech: and not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished: but their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ. But even unto this day, when Moses is read, the vail is upon their heart. Nevertheless when it shall turn to the Lord, the vail shall be taken away. Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty. 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.
