How do we know the doctrine of salvation in Romans is true?

The doctrine of salvation found in Romans is rooted in the detailed and systematic teaching of the Apostle Paul, who articulates the gospel doctrine of salvation across the first eleven chapters of the epistle. This letter is recognized as a foundational text for Christian doctrine, providing clarity on the nature of sin, grace, and redemption through Jesus Christ. Furthermore, the transformative effects of this doctrine in the lives of believers serve as evidence of its truth. The Holy Spirit works within the hearts of believers, bringing about change and enabling them to live in accordance with the will of God, which strongly supports the authenticity of Paul's teachings on salvation.
