Why is Christ's sacrifice central to the faith?

The sacrifice of Christ is central because it meets the just requirements of God's law and offers atonement for sin. The brazen altar in the courtyard points to Jesus as the ultimate sacrifice who bore the penalty for our sins. As stated in Exodus 29:37, anything that touches the altar becomes holy, denoting the transformative power of Christ's sacrifice. It is through His death and resurrection that believers are justified and granted access to the presence of God, making His sacrifice essential for salvation.
