How do we know Christ's righteousness is imputed to us?

In Reformed theology, the idea of imputed righteousness is crucial. Romans 5:19 indicates that through Adam's disobedience many were made sinners, but through Christ's obedience, many will be made righteous. This means that Christ's perfect life and sacrificial death fulfill all requirements of God's law on behalf of believers. He was without sin and His righteousness is counted as ours when we place our faith in Him. This legal standing allows us to be justified before God, as affirmed in 2 Corinthians 5:21, where it describes how God made Christ to be sin for us that we might become the righteousness of God in Him.
