Why is it important for Christians to understand Jesus' righteousness?

Jesus' righteousness is of utmost importance for Christians as it is through His perfect righteousness that believers are justified before God. Psalm 45 notes, 'He loves righteousness and hates wickedness,' which underscores the character of Christ and the means by which He interacts with humanity. For Christians, this means that through faith in Christ, they receive His righteousness as a gift, thus transforming their standing from guilty sinners to declared righteous in His sight. This foundational doctrine is what gives believers assurance of their salvation and encourages them to reflect Christ in their lives.
