Why is the cross central to Christianity?

The centrality of the cross in Christianity lies in its representation of Christ's atoning work. He bore the sins of His people on the cross, suffering the full weight of God's wrath that they deserved. This act of substitution satisfies divine justice and makes possible the forgiveness of sins. As seen in Psalm 22, the prophetic insights into Christ's sufferings reveal the necessity of His cross to redeem and justify sinners fully. The resurrection following His crucifixion confirms His victory over sin and death, assuring believers of their redemption and the reality of eternal life through Him.
