How do we know Christ's righteousness is important for salvation?

The significance of Christ's righteousness in the context of salvation is profound, as it constitutes the basis for how believers are deemed acceptable before God. Romans 3:21-22 teaches that the righteousness of God is revealed through faith in Jesus Christ for all who believe. This righteousness is not merely an abstract concept; it is the perfect fulfillment of God's law by Christ, who lived sinlessly. Thus, when believers trust in Christ, they are justified, meaning they are declared righteous and acquitted of sin due to Christ's merits rather than their own. This underscores the core tenet of justification by faith alone (Sola Fide), central to Reformed theology.
