Why is Christ's cross work central to worship and walk?

The centrality of Christ's cross work in worship and walk cannot be overstated. In Numbers 7, the altar symbolizes the essential need for atonement and sacrifice, which points directly to the cross of Christ. The apostle Paul emphasizes this in Galatians 6:14, noting that the only thing he will boast in is the cross of Christ. True worship is thus grounded in understanding and appreciating what Christ accomplished at the cross, as it is through His sacrifice that believers receive justification, reconciliation, and the means to worship God acceptably. Our walk, therefore, must reflect this reality and be aligned with the righteousness achieved through His cross work.
