How do we know the doctrine of imputed righteousness is true?

Imputed righteousness is a cornerstone of Reformed theology and is based on the belief that sinners stand condemned before God without any righteousness of their own. In the sermon, it is articulated that we cannot approach God based on our own deeds, but we stand 'clothed in His righteousness'—the righteousness of Christ. The Apostle Paul underscores this in his letters, which affirm that believers are justified not by their works but through faith in Christ who kept the Law perfectly. This truth assures us that we can confidently approach God, not in our merit but based on the righteousness given to us by Christ.
