How does Christ's sacrifice secure our salvation?

The sacrificial death of Christ is the cornerstone of Christian faith, as it not only satisfies divine justice but also provides redemption for sinners. In Galatians 3:13, it is stated that 'Christ hath redeemed us from the curse of the law,’ signifying that through His blood, believers are no longer under the law's condemnation. His resurrection further affirms this victory, demonstrating God's acceptance of Christ's sacrifice. As a result, we are justified—declared righteous in God’s sight—ensuring our eternal security and unbreakable union with Christ. Therefore, the work of Christ is not merely a past event but the basis on which believers anchor their hope and assurance of salvation.
