“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, a minister in the holy places, in the true tent that the Lord set up, not man.” Hebrews 8:1-2
In Hebrews 8, we see the author’s focus shift toward discussing the new covenant that Christ enacted for us. The author tells us that Christ is qualified to be the high priest of this new covenant because He serves in the true tabernacle in heaven, and not in the earthly tabernacle which is only a “sketch and a shadow” of its heavenly counterpart. The earthly tabernacle serves only to give us a glimpse of what we will see when we are in God’s presence in heaven.
In this same fashion, God’s old covenant with Israel is but a sketch, or a blueprint, of the covenant that He would make with us through Christ. To support this position, the author quotes Jeremiah 31, a passage in which God explains the new covenant’s coming. But before we can understand the new covenant, we must first understand the old covenant that preceded it.
After God freed Israel from slavery in Egypt, He led them to Mt. Sinai. At Sinai, God gave Israel the Law, and He told them that He had called them to be His people and that He would be their God. Israel would show their commitment to keeping the covenant by keeping God’s commandments. But this proved to be a problem, for Israel could never live up to these terms. They were never able to live according to God’s standard. As soon as they settled in the Promised Land, there arose a generation who did not know the Lord. From there, the situation only became worse. With each generation, Israel strayed further and further from the Lord. By the prophet Jeremiah’s time, God had decided it was time to make a new covenant.
In Jeremiah 31, the passage that the author of Hebrews quotes from, God tells Jeremiah that this new covenant would not be like the previous one, it would be better. God ensured that the new covenant would be better by vowing to fix the old covenant’s major flaw—us. Israel could never keep the law and keep the covenant because of their fallen nature. They were sinful beings, just the same as we are today. They couldn’t keep the law because their sinful nature made them incapable of doing so.
But God would do something different in the new covenant; He would change us. To ensure the success of the new covenant, God would change our human nature. He would give us new hearts upon which He has written His law. He would fill us with His spirit, and He would make us capable of living up to His standard and being His people. When God brings us to Himself through Christ, He makes us new creatures who seek only Him.
Living as the people of God requires us to be incredibly honest about what is in our hearts. We cannot be God’s people if we are still holding on to things from our old lives and from our old, sinful hearts. We must thoroughly examine our hearts, and if we see that we are holding on to sin, we must humbly go before God and ask for His forgiveness. We must pray that He remove that sin from us, and we must ask that He give us the strength we need to live as He calls us to live.
