The superiority of the new covenant is that it finally removes our sin, not that it provides an eternal forgiveness apart from our moral transformation.

The above verse leads scholars to believe Christ has redeemed us eternally in that we are perpetually forgiven no matter what we do. Obviously, such a position does not agree with the Apostle Paul when he wrote that if we Christians continue living in the sins of the flesh we shall not inherit the Kingdom of God. Something obviously is amiss with the current conclusion regarding Hebrews 9:12.

Christ indeed did obtain eternal redemption for us. That redemption begins as we receive by faith the atonement made through the blood of Calvary. Then it continues through the work of the Holy Spirit until finally we are delivered from the compulsions of sin. We continue without condemnation because the righteous requirements of the Law of Moses are imputed to us; but the righteous requirements of the Law of Moses are imputed to us only as long as we are following the Holy Spirit in the program of removing sin from us.

In order that the righteous requirements of the law might be fully met in us, who do not live according to the sinful nature but according to the Spirit. (Romans 8:4)

"Who do not live according to the sinful nature but according to the Spirit"!

Christian thinking is incorrect when it maintains that righteousness is ascribed to us even though we continue to live according to the sinful nature.

What a gross error this is in Christian thinking!

The truth is, the difference between the two covenants is not that the new covenant is a superior forgiveness but that the new covenant through its many aspects of enabling grace guides and empowers us to put to death the deeds of our sinful nature.

How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death,  so we may serve the living God! (Hebrews 9:14)

The new covenant invites us to look up from the Law of Moses and serve Christ without condemnation. But we are free to "serve the living God," not free to continue in our sins. The atoning blood cleanses us from all unrighteousness provided we are walking in the light of God's will.

For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant. (Hebrews 9:15)

The above verse does not mean Christ sets us free from the guilt of the sins committed under the first covenant, but from the sins themselves.

Then Christ would have had to suffer many times since the creation of the world. But now he has appeared once for all at the end of the ages to do away with sin by the sacrifice of himself. Just as man is destined to die once, and after that to face judgment, So Christ was sacrificed once to take away the sins of many people; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him. (Hebrews 9:26-28)
