It is true that the law of Moses was good and true and it inspired by God. Hebrews does not deny it. But that law was a covenant, with penalty clauses. One that none of us were able to keep.
We cannot be holy. We cannot even fulfil regulations based on righteousness, which is the law and religion. We need Grace, which is God’s mercy to us, trapped in our slowly converging hells of our own making.
Praise God that he sent Christ as a mediator and our defence. It is not our actions, but God’s mercy, that saves.
8 Now the point in what we are saying is this: we have such a high priest, one who is seated at the right hand of the throne of the Majesty in heaven, 2 a minister in the holy places, in the true tent that the Lord set up, not man. 3 For every high priest is appointed to offer gifts and sacrifices; thus it is necessary for this priest also to have something to offer. 4 Now if he were on earth, he would not be a priest at all, since there are priests who offer gifts according to the law. 5 They serve a copy and shadow of the heavenly things. For when Moses was about to erect the tent, he was instructed by God, saying, “See that you make everything according to the pattern that was shown you on the mountain.” 6 But as it is, Christ has obtained a ministry that is as much more excellent than the old as the covenant he mediates is better, since it is enacted on better promises. 7 For if that first covenant had been faultless, there would have been no occasion to look for a second.
