How do we know Jesus is our perfect righteousness?

The concept of Jesus as our perfect righteousness is rooted in the Reformed understanding of justification by faith. Romans 5:19 states, 'For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.' Jesus embodies the perfect standard required by God, fulfilling the law completely. As believers, we are viewed as righteous in Him, allowing us to claim that we have never sinned when we identify ourselves in Christ. This understanding shifts the focus from our imperfect works to Christ's perfect obedience on our behalf, underscoring the grace of God in salvation.
