Hebrews 8:3-6, A priest offers both gifts and sacrifices
In the Old Testament the office of priest was a sacred office that only a limited number of people could partake in according to their lineage. The tribe of Levi was chosen as the individuals who would be the priests of the covenant between Israel and God. The office meant that they would close the gap between man and God by ministering on behalf of man to God, this meant that they would be the ones who offered sacrifices and gifts on their behalf to God. This was a sacred act and we see in Samuel where the kingdom of Israel was stripped from Saul because he chose to make a sacrifice to God instead of waiting on the prophet Samuel to do so. Hebrews 8:3-6 tells us that the office of high priest was ordained for the purpose of offering gifts and sacrifices to God but now we have one in Jesus Christ who goes well beyond that and acts as our mediator to God in the new covenant.
No earthly priest can live up to the gift and sacrifice that Jesus offered on our behalf. They offered what was given to them on man’s behalf, but Jesus offered His very own life as a sacrifice for the sins of all mankind. He didn’t have to wait for someone to bring Him a sacrifice to be made, He stepped down from His Heavenly throne and placed His life on the altar of sacrifice on our behalf. Yet Jesus didn’t stop there He gave us a better covenant than that which was offered to the children of Israel. The old covenant brought about death while the new covenant allows an escape from death to anyone who chooses to accept it. Jesus made a way to escape the punishment we all justly deserve from our rebellion and in towards God. All we must do is believe in Jesus as our Lord and Savior, repent of our sins (turn from them) and accept the gift and sacrifice He has made available to us all. No earthly priest could possibly offer what Jesus fulfilled on our behalf, only God could do this.
