Jesus Christ is the High Priest of a new, everlasting covenant that will never be forgotten. His ministry brings eternal salvation to all who obey Him.
In those days and in that time, declares the Lord, the people of Israel and the people of Judah shall come together, weeping as they come, and they shall seek the Lord their God. They shall ask the way to Zion, with faces turned toward it, saying, “Come, let us join ourselves to the Lord in an everlasting covenant that will never be forgotten.” Jeremiah 50:4-5
In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence. Although he was a son, he learned obedience through what he suffered. And being made perfect, he became the source of eternal salvation to all who obey him, being designated by God a high priest after the order of Melchizedek. Hebrews 5:7-10
Jeremiah watched while Judah followed Israel into ruins. God had decreed severe discipline upon His people who shamefully broke His covenant. Clearly, the old covenant and the old priesthood were not sufficient to save the nation. But God showed Jeremiah that there would be a new covenant–one that would never fail. What covenant? The one made with the sacrifice of the Son of God, Jesus Christ, who paid the ransom for all the sins of all who would obey Him.
The Aaronic priesthood could not save sinners, although (as we can now see) it was meant only to reveal the need for a better priesthood and a better covenant. The old covenant was not a failure. It actually fulfilled its limited and designated function. It pointed to the Messiah, the Holy One of Israel, who alone could make atonement for sins as He had none of His own for which to atone. The old covenant was not a failed experiment on God’s part but a plan to reveal the greater glory that would come through the eternal never-to-be-forgotten covenant with Jesus Christ.
Think about it
The failures of Judah and Israel to obey the old covenant mirror our own failures to live in perfect holiness. Like Ancient Israel, we have all fallen short of the glory of God (Romans 3:23). But by faith in Christ, we have a high priest, appointed by God, who will minister forever not under the weakness of Aaron’s priesthood but after the order of Melchizedek. Be sure you are not dull of hearing but firmly and clearly grasp the basis of your salvation. Eternal life or death depends on it.
