“But Jesus has now obtained a superior ministry, and to that degree he is the mediator of a better covenant, which has been established on better promises. For if that first covenant had been faultless, there would have been no occasion for a second one. But finding fault with his people, he says: ‘See, 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’ …. By saying a new covenant, he has declared that the first is obsolete. And what is obsolete and growing old is about to pass away” (Hebrews 8:6-8,13, CSB).

The Hebrews writer explained that the Old Testament covenant law has been replaced with the new covenant of the gospel of Christ. Although the old has been replaced with the new, both were necessary functions of God’s unfolding plan of redemption for rebellious humanity.

But, the Hebrews writer said the new covenant of the resurrected Christ was actually the fulfillment of the temporary atoning measures provided in the Mosaic law. In other words, the ministry of Christ was superior to the Mosaic law because it was founded on better promises than the old covenant. While the Mosaic law convicted of sin, the gospel of Christ conveyed eternal life.
