Why is the altar important for Christians?

In Christian theology, the altar symbolizes the sacrifice of Jesus Christ, representing the atonement for sin and the everlasting redemption He provides for His people. The altar is where believers gather to worship and recognize the price Jesus paid for their sins. Hebrews 9:12 explains that Christ entered into the holy place not with the blood of goats and calves, but by His own blood, securing eternal redemption. This theme of Christ as the altar emphasizes that through His sacrifice, believers are made righteous and can approach God in worship.
