Why is it important for Christians to understand their justification before God?

Justification is a foundational doctrine of the Christian faith, reflecting God's declaring sinners righteous based on Christ’s atoning work. Hebrews emphasizes that Christ is the mediator of the new covenant, illustrating that justification is granted not because of our merit but because of God's sovereign choice and grace. This truth relieves believers from the burden of trying to achieve righteousness through their deeds. Instead, it allows them to live in the freedom of knowing they are accepted and loved by God, providing a solid foundation for their faith and assurance in Him.
