Leviticus 1-3…The burnt offering, the grain offering, and the fellowship offering.
Burnt offerings were the propitiatory sacrifices in ancient Israel. For God to maintain His justice, He must punish sin. To forgive at the expense of His just wrath would be inconsistent with His character; according to His holiness, those who have sinned must die (Gen. 2:15–17; Rom. 6:23). Once the Lord satisfies His wrath, it passes away, allowing fellowship between the Creator and His people. The burnt offering temporarily accomplished propitiation (satisfied God’s wrath) under the old covenant (2 Chron. 29:7–8), allowing God’s wrath to be appeased against Israel.
In this section of scripture (Leviticus 3 in particular), we also see God’s concern for His glory being made known through a corporate witness. God has always wanted His people to live together in unity, love, and holiness, so His name would be glorified. Today, this is done practically through the local church. This is Christ’s plan for his people, and it includes you if you’re a Christian. Commitment to a local church is they way in which we live out all the “one another” imperatives in the New Testament.
