Why is understanding Christ's finished work important for Christians?

The finished work of Christ is central to the Christian faith as it provides the foundation for assurance of salvation. Jesus's sacrificial death and resurrection secured eternal redemption for those He loves, as affirmed in Hebrews 9:12. This truth emphasizes that salvation is not contingent on human action but wholly on Christ's atoning work. The security that believers have, knowing they cannot be separated from Christ's love, encourages them to live in faith and obedience, resting in the certainty that they are accepted by God. John the Baptist's message to 'behold the Lamb of God' encapsulates this truth, urging believers to keep their focus on Christ.
