How does Christ fulfill the role of both altar and sacrifice?

Christ fulfills the dual roles of altar and sacrifice uniquely and profoundly. In the Old Testament, the brazen altar was the place where sins were atoned for through sacrifice, but it was merely a shadow of the reality found in Christ. As stated in Hebrews, we have an altar in Christ where He satisfied God's justice by His own sacrifice. He bore the weight of judgment while being both the perfect priest and the flawless offering. This duality is fundamental to understanding the gospel, as it illustrates how Jesus has made a way for humanity to be reconciled to God through His death and resurrection, highlighting the depth of God's love and grace.
