Relationships under the law were written on stone. Relationships of the new covenant were written in our hearts with the Spirit of the living God. Paul encouraged the Corinthians and us, revealing that glorious difference between the law and the new covenant.
God’s old covenant people were under the Law. Not just the 10 Commandments, written on stone, but many rules and regulations. We are God’s new covenant people, sealed with the Holy Spirit. God “has blessed us with every spiritual blessing in the heavenly places in Messiah” (Eph 1:3), … “In him you also, having heard the word of the truth, the Good News of your salvation—in whom, having also believed, you were sealed with the promised Holy Spirit, who is a pledge of our inheritance, to the redemption of God’s own possession, to thepraise of his glory” (Eph 1:13-14).
The new covenant contrasted with the Law.
Paul, a servant of the new covenant. “1 Are we beginning again to commend ourselves? Or do we need, as do some, letters of commendation to you or from you? 2 You are our letter, written in our hearts, known and read by all men, 3 being revealed that you are a letter of Messiah, served by us, written not with ink, but with the Spirit of the living God; not in tablets of stone, but in tablets that are hearts of flesh.
The letter of the law kills, but the Spirit gives life. “4 Such confidence we have through Messiah toward God, 5 not that we are sufficient of ourselves to account anything as from ourselves; but our sufficiency is from God, 6 who also made us sufficient as servants of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life. 2 Corinthians 3:1-6 WMB
The glory of old covenant is exceeded by the glory of the new covenant.
The service of death vs the service of the Spirit 7 But if the service of death, written engraved on stones, came with glory, so that the children of Israel could not look steadfastly on the face of Moses for the glory of his face, which was passing away, 8 won’t service of the Spirit be with much more glory?
The service of condemnation vs. the service of righteousness 9 For if the service of condemnation has glory, the service of righteousness exceeds much more in glory. 10 For most certainly that which has been made glorious has not been made glorious in this respect, by reason of the glory that surpasses. 11 For if that which passes away was with glory, much more that which remains is in glory.
The veil over the glory 12 Having therefore such a hope, we use great boldness of speech, 13 and not as Moses, who put a veil on his face so that the children of Israel wouldn’t look steadfastly on the end of that which was passing away. 14 But their minds were hardened, for until this very day at the reading of the old covenant the same veil remains, because in Messiah it passes away. 15 But to this day, when Moses is read, a veil lies on their heart.
We all with unveiled face seeing the glory 16 But whenever someone turns to the Lord, the veil is taken away. 17 Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty. 18 But we all, with unveiled face seeing the glory of the Lord as in a mirror, are transformed into the same image from glory to glory, even as from the Lord, the Spirit. 2 Corinthians 3:7-18 WMB
