Why is the concept of the imputed righteousness of Christ important?

The doctrine of imputed righteousness is crucial for understanding how believers can stand before a holy God. According to 2 Corinthians 5:21, Christ was made to be sin for us, so that we might become the righteousness of God in Him. This means when Christ's righteousness is credited to us, our sins are covered, and we can enjoy fellowship with God. It emphasizes that salvation is entirely a work of God, removing any ground for boasting in human merit. Recognizing this truth fosters a deep reliance on Christ and His sufficiency.
