2 Corinthians 3:17-18

Young's Literal Translation

¹⁷ And the Lord is the Spirit; and where the Spirit of the Lord [is], there [is] liberty;

¹⁸ and we all, with unvailed face, the glory of the Lord beholding in a mirror, to the same image are being transformed, from glory to glory, even as by the Spirit of the Lord.
