How do we know that Christ is our perfect altar?

In the context of worship and sacrifice, Christ is identified as our altar, as indicated in Hebrews 13:10. Throughout the Old Testament, altars were places of sacrifice where blood was shed for sin atonement. Christ's sacrifice at Calvary not only fulfills the requirements for propitiation but also serves as the ultimate altar for His people. His blood speaks peace for our sin, unlike the sacrifices of the Old Testament that pointed to Him. Only in Christ do we find acceptance with God and a means to cover our sinful state, making Him our single and sufficient altar.
