How do we know that we are justified by faith alone?

The assurance of our justification by faith alone is rooted in the consistent teaching of Scripture. Romans 3:20-24 clarifies that no one can be justified by the deeds of the law, for by the law comes the knowledge of sin. Instead, we receive justification freely by God’s grace through the redemption found in Christ Jesus. This doctrine is affirmed across the New Testament, emphasizing that Christ’s atoning work is the basis of our justification, which is applied to believers through faith.
