Why is the confession of Jesus's righteousness important for Christians?

Confessing Jesus as the righteous man is crucial for Christians as it aligns with the core of the gospel message: that in Christ, believers find their justification before God. As expressed in Romans 4, being justified through faith in Christ's righteousness contrasts starkly with the futility of relying on one's own works. The acknowledgment of Christ as the righteous one establishes that He is our representative and mediator, fulfilling the law on our behalf. Consequently, through faith, Christians are clothed in His righteousness, which is crucial for standing faultless before a holy God on the day of judgment.
