What does the Bible say about Christ as our altar?

According to Hebrews 13:10, Christ is our altar. Everything in the Old Testament worship system, including the law and sacrifices, served as foreshadows of Him. The temple, the tabernacle, and the sacrificial offerings were all pointers leading to Christ, who embodies the fulfillment of these elements as the ultimate sacrifice for sin. Just as the physical altar was necessary for the Israelites to approach God, Christ, our spiritual altar, is the only access we have to God, enabling us to offer acceptable worship and sacrifice through Him alone.
