Commentaries:
In verses 8-12, Paul quotes from Jeremiah 31:31-34. The writer begins by telling us that God found fault with the men of old, and this leads to the quotation from Jeremiah 31 in Hebrews 8:8.
From the failures of the past, Jeremiah turned his vision to the future. There are four significant things prophesied by Jeremiah and quoted by Paul about the new covenant in verses 10-12:
First, the New Covenant is inward and dynamic: It is written on the hearts and minds of the people. A shortcoming of the Old had been its outwardness. It had divinely given laws, but it was written on tablets of stone. Jeremiah looked for a time when people would not simply obey an external code but would be so transformed that God's own laws would be written in their inmost beings.
Second, there is a close relationship between the God who will be "their God" and the people, he says, who will be "My people." The change from the Old Covenant to the New Covenant is that while the formula of the covenant remains the same from age to age, it is capable of being filled with fresh meaning to a point where it can be described as a "new" covenant. "I will be your God" acquires fuller meaning with every further revelation of the character of God.
Third, all who enter it will have knowledge of God. There will be no need for a person to instruct his neighbor. The word rendered neighbor in verse 11 means "citizen," and thus a "fellow-citizen." Jeremiah moves from the wider relationship in the community to the narrower relationship in the family, saying that in neither case will there be a need to exhort anyone to know God because everyone will know Him.
This does not mean that under the conditions of the New Covenant there will be no place for a teacher. There will always be the need for those who have advanced in the Christian way to pass on to others the benefit of their knowledge. Rather, the meaning is that the knowledge of God will not be confined to a privileged few (as with the priesthood of ancient Israel). All those under the New Covenant will have their own intimate and personal knowledge of their God.
Fourth, under the New Covenant, sins are forgiven. Following repentance of sins and acceptance of the sacrifice of Jesus Christ, sins are forgiven. The superior sacrifice of Christ is offered once and for all, paying the penalty of sin for those who repent.

The Law's Purpose and Intent
The ultimate fulfillment of this process will culminate when we are completely composed of spirit, and God's law will be our first nature, not just second nature. But, while we are in an embryonic stage, the process has already begun in us, incrementally, as God gradually displaces our carnality and sin, replacing it with His Holy Spirit, leading to righteous behavior and godliness. Actually, no human being is completely converted, but many people are in various stages of conversion.
Conversion, then, is a life-long process in which we move from a reactive approach to lawkeeping—motivated by rewards and punishments—to a proactive approach—motivated by a deeply placed inner desire to yield and comply to the law's principles, knowing intrinsically from experience that they work for the good and harmony of all. (Proactive is a term author-speaker Steven Covey uses to distinguish internal motivation to do or accomplish something as opposed to external motivation.)

Righteousness from Inside-Out
These verses outline some major objectives within the workings of the New Covenant. Merciful forgiveness for breaking God's laws is a major one. The author provides an intriguing overview of God's objectives using the means of the New Covenant as His tools. This overview provides a clear statement that God will be an even more hands-on Creator, working in His people's behalf more than ever before. It clearly states that law-keeping and sinlessness are major objectives in its institution, giving no indication of any kind that moral laws are being “done away.”
The excitement is building toward seeing what He will lead each of us to become in our lives. It should be abundantly clear that God's law will be a primary tool in creating us into the image of Jesus Christ so that throughout eternity we are prepared to follow Him wherever He goes, and He kept God's laws perfectly.

Why Hebrews Was Written (Part One)
The theme of the Day of Atonement is reconciliation, becoming at one with God through the forgiveness of sin. It starts the salvation process off. Each year, on the Day of Atonement, Israel's sins were symbolically transferred to the Tabernacle by having the first goat's blood sprinkled on it. The blood symbolically contained their sins. The blood was sprinkled on the Mercy Seat, transferring their sins, then, to God's throne, where they were forgiven. That is the picture behind this.
So the author says that the Tabernacle, all of its furniture, and all of its ceremonies and rituals used to accomplish atonement (at-one-ment) with God were types. These symbols stood in their place with good purpose, but only until they were replaced with a more effective reality. Christ went into the Holy of Holies with His own blood.
Now we need to put this into a bigger context, the whole book of Hebrews. The overall theme of Hebrews can be described by such words as better, superior, greater. Chapter 1 begins by telling us that Christ is greater than angels. Chapter 2 shows us that the goal given to us in the gospel of the Kingdom of God is so far superior to anything man has ever been offered before that there is no comparison.
In chapter 3, Christ is far greater than Moses. Beginning in chapter 4 and on into chapter 6, the comparison is made with Aaron, and again, Christ is greater. In chapter 7, we find a comparison with the Melchizedek priesthood and the Levitical priesthood. The Melchizedek priesthood is greater, superior, better than Aaron's.
In chapter 8, the covenant is introduced. The New Covenant is superior to the Old Covenant. The theme continues right on into chapters 9 and 10, because they are concerned with the superiority of the sacrifice of Christ to the things of the Old Testament - the Tabernacle, its furniture, and all of its ceremonial systems. But they were only imposed for a time, until something better was provided by God. It is clear, then, that God's intent with the sacrificial system was that it would only be imposed temporarily.
