Why is the finished work of Christ essential for believers?

The finished work of Christ is the cornerstone of the Christian faith. It affirms that Jesus fully satisfied the demands of the law by living a perfect life and offering Himself as a sacrificial atonement for sin. As Romans 5:1 explains, through Christ, we have peace with God because we are justified by faith. This work removes the barrier of sin, allowing believers to stand righteous before God, not through their own efforts, but through Christ’s righteousness imputed to them. Therefore, the finished work of Christ provides assurance of salvation, peace, and an unwavering hope in the promises of God.
