In the last post I explained that the original covenants YHWH created are still relevant and in many ways still active. But I certainly realize that some parts of each of the covenants are aging, as Paul says in Hebrews 8:13. As time goes on, more aspects of each covenant has gotten closer to their fulfillment, and the more aspects that have been fulfilled, the fewer that are left to be fulfilled. For instance, in the Abrahamic Covenant, the Lord promised Israel a land of their own, and now they have it (and will never be ejected from it again, by the way). Because of this, Abraham’s descendants have indeed blessed the gentile world as well as the Hebrew world.
Under the Mosaic Covenant, the Lord created the sacrificial system, and the whole purpose of all those sacrifices was fulfilled in Jesus’ death. Now, when it comes to the purpose of the Law, which was to show men what YHWH’s principles, attributes, and morals are, and what pleases and displeases Him, will continue until at least the Millennial Kingdom (how else will we know what God’s definition of sin is?).
We can even check off several aspects of the Newest Covenant. For example, the son of King David (the Messiah Jesus) has already come and atoned for our sin. However, does that mean that the New Covenant is now obsolete, just because it is 2000 years old and some of its terms are fulfilled? No, of course not. Yes, the Abrahamic Covenant is further down the path of being completely fulfilled, and the Mosaic Covenant has many elements that are now fulfilled, but many are still yet to be fulfilled. Even the New Covenant has some elements fulfilled but much more are left to be accomplished (such as Christ’s return, the salvation of all Israel, the destruction of Armageddon, and setting up the Millennial Kingdom, just to mention a few). All three covenants are needed, and they are all still valid. It is just that some aspects of the covenants are closer to having every element of their purpose completed than the others.
Let me give you a very short analogy and I will let this go (for a little while, anyway). When you build a house, it has several basic components: you start by preparing the ground, then you lay a cement slab, frame the walls, add a roof, put the shingles on, and then the siding, install all the electrical systems and plumbing fixtures, drywall, etc, etc. Now, since you have prepared the ground, poured the slab, and completed that portion of the job, does that mean that the slab and its purpose are dead and gone? Of course not. You need them to complete the building, don’t you?
The entire house relies on that slab. In fact, that slab was prepared to carry the load that will be built on it. If you were to dissolve the slab, there is no way to build and complete the house. That is the way it is with God’s covenants—they were all necessary and they remain necessary.
