We know justification is by faith alone through Scripture, specifically Romans 3:28, which states that a man is justified by faith without the deeds of the law.
The doctrine of justification by faith alone is foundational to Reformed theology, affirmed in Romans 3:28, where Paul asserts that we are justified by faith apart from the works of the law. This emphasizes that faith is a gift from God, not a work we perform, ensuring that all boasting is excluded. John Gill comments that this law refers to the doctrine of the gospel, demonstrating that even the vilest of sinners are justified by faith in Christ's righteousness alone. It highlights the grace of God in saving unworthy sinners, showing that our standing before God is based solely on His mercy and not our own efforts.
