What does it mean that believers are righteous in Christ?

The righteousness of believers is rooted in their union with Christ, not in their own works. 2 Corinthians 5:21 states, 'For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.' This profound truth signifies that through faith, believers are robed in Christ's righteousness, declared just in God's sight. Just as Noah was deemed righteous within a wicked generation, so too are believers justified in Christ, securing their place in the eternal ark of salvation from judgment.
