The new replaced the old

In the Old Testament: Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and with the house of Judah— not according to the covenant that I made with their fathers in the day that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them, says the LORD. I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people. (Jer 31:31-33)

In the New Testament: Christ is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance. (Heb 9:15) He has made us competent as ministers of a new covenant—not of the letter (the law) but of the Spirit (Christ); for the letter kills, but the Spirit gives life. (2Co 3:5-6) So we must minister the new and not the old. Hear Him!
