Referenced from my instagram post, about the freedom where the spirit of the Lord is:
Are we beginning to commend ourselves again? Or do we need, as some, letters of commendation to you or from you? You are our letter, written in our hearts, known and read by all men; being manifested that you are a letter of Christ, cared for by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
Such confidence we have through Christ toward God. Not that we are adequate in ourselves to consider anything as coming from ourselves, but our adequacy is from God, who also made us adequate as servants of a new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.
But if the ministry of death, in letters engraved on stones, came with glory, so that the sons of Israel could not look intently at the face of Moses because of the glory of his face, fading as it was, how will the ministry of the Spirit fail to be even more with glory? For if the ministry of condemnation has glory, much more does the ministry of righteousness abound in glory. For indeed what had glory, in this case has no glory because of the glory that surpasses it. For if that which fades away was with glory, much more that which remains is in glory.
Therefore having such a hope, we use great boldness in our speech, and are not like Moses, who used to put a veil over his face so that the sons of Israel would not look intently at the end of what was fading away. But their minds were hardened; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed in Christ. But to this day whenever Moses is read, a veil lies over their heart; but whenever a person turns to the Lord, the veil is taken away. Now the Lord is the Spirit, and where the Spirit of the Lord is, there is liberty. But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as from the Lord, the Spirit.
(2 Corinthians 3:1-18, NASB)
Context of Moses:
Moses was the leader of the Israelite people during the years in the desert after they left Egypt. He received the 10 commandments from God, atop Mount Sinai. After spending 40 days on the mountain, with God, Moses came down glowing, radiating the glory of God. He was shining and the people were afraid to approach him, so he wore a veil as he talked to them.
Read through exodus 19-34 for a rough idea, or those two chapters to understand the place as whole.
