Then Moses said to Aaron, “Draw near to the altar and offer your sin offering and your burnt offering and make atonement for yourself and for the people, and bring the offering of the people and make atonement for them, as the Lord has commanded.”
And he took a cup, and when he had given thanks he gave it to them, saying, “Drink of it, all of you, for this is my blood of the covenant, which is poured out for many for the forgiveness of sins.”
As first instructed back in Exodus 29, Leviticus 8 records the ordination of Aaron and his sons as priests. It is a glorious time – a monumental event in the history of the Israelite people! The priesthood has been established! God has provided a way for a sinful people to draw near to a holy God!
Leviticus 9 records Aaron’s first priestly duties. It sets forth a model of worship that remains relevant to the believer today…
- He begins by offering a sin offering first for himself and then for the people. Having atoned for the sins of the congregation,
- He offers a burnt offering as a sign of total devotion and thanksgiving to the Lord.
- Finally, Aaron offers a peace offering as a symbol that God and the people have been reconciled through the blood of the offerings.
God was pleased with Aaron, and the offerings were accepted! Aaron and the priesthood would now act as the mediator between God and the people.
Leviticus 10 is a severe reminder that worship is not just a list of duties to be performed, but must come from an undivided heart. All four of Aaron’s sons failed to keep a portion of the priestly duties. Aaron’s oldest sons were killed for offering “unauthorized fire.” The implication was that they were cavalier in their duties. God does not tolerate flippant pride. Aaron’s younger two sons did not eat the sin offering as commanded. But they were spared because their motivation was out of fear for the holiness of God. God has always been more concerned with the heart than with outward actions.
In fact, Jeremiah prophesied that there would be a new covenant and it would be written on the heart.
“Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel… I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.
Jesus is the mediator of this new covenant – the covenant of grace. He institutes “the Lord’s supper” as he eats his last meal with the disciples recorded in Matthew 26. Jesus says that this is the “blood of the covenant which is poured out for many for the forgiveness of sins” (Matthew 26:28). We celebrate this new covenant each time we take communion. It is a meal that points forward to a day when we will eat and drink with Jesus face to face…
“I tell you I will not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom” (Matthew 26:29).
Until that day, we are called to worship our God with all of our heart…
- Because of Jesus’ perfect sin offering, we can draw near to God.
- We make our burnt offering as we devote our bodies as a living sacrifice, holy and acceptable to the Lord (Rom 12:1),
- And we make our peace offering as we confess the gospel of reconciliation to the world.
According to Peter, we are now the priesthood! And we are to offer “spiritual sacrifices acceptable to God through Jesus Christ” (1 Pet 2:5).
