The third chapter of the book of 2nd Corinthians is loaded with blunt points: All the laws of God and Moses, including the ten commandments have all been fulfilled in Christ on the cross. We are now under a new and better covenant: full of grace and love, rather than vengeance and condemnation (Heb 12:24).
God has made us able ministers of the New Covenant. If the old covenant of death, written and engraved in stones—that is, the ten commandments—was glorious, and made the face of Moses to shine such that people couldn't look at his face, how much more glorious do you perceive the magnitude of the glory of ministration of righteousness! A more excellent glory arrived in Christ.
O friend, for emphasis, the old testament has been abolished. It has been done away with (2 Cor 3:6-15). Eph 2:15 says:
“Having abolished in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace.”
This was also reiterated in Col 2:14-17. You are not under the laws and ordinances of the old covenant. It has been done away with and abolished in its entirety and replaced with the better and gracious new covenant at Calvary. (Exo 24:12, 31:18, 32:15; Dt 4:13, 5:22, 10:4).
