How do we know that Christ is our altar and sacrifice?

In Christian theology, Christ is recognized as both the altar and the sacrifice that allows believers to approach God. As Hebrews 13:10 indicates, we have an altar in Christ, which the Jewish worshippers had no right to partake in, reflecting the transition from Old Testament rituals to the New Covenant established in Christ. The sacrifices of the Old Testament, including the daily offerings and the special feasts, typified the ultimate sacrifice of Jesus, which fully satisfies God's justice for His people. His dual role as Savior validates the practices of worship through His work, allowing all believers to come boldly to the throne of grace.
