What role does Christ's righteousness play in our salvation?

As articulated in 2 Corinthians 5:21, 'For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.' Our salvation hinges upon the righteousness of Christ, which is imputed to believers. Isaiah 54:17 reinforces this by proclaiming that 'their righteousness is of me,' depicting how our standing before God is exclusively on account of Christ’s perfect obedience. Thus, it is through His righteousness that believers find acceptance and peace with God.
