How do we know that the doctrine of justification by faith is true?

The doctrine of justification by faith is grounded in the teachings of Scripture, which convey that we are justified before God solely through faith in Jesus Christ. Paul emphasizes in Galatians 3:1-5 that reliance on works or the law to attain righteousness is a fundamental misunderstanding of the gospel. He highlights the clarity with which Jesus Christ was portrayed as crucified, asserting that our faith in His atoning sacrifice alone is how we are justified. Furthermore, Romans 4 outlines that Abraham was justified by faith before any works were present, establishing a biblical precedent that faith, not works, is the means through which justification is received. Thus, the truth of justification by faith is deeply rooted in the biblical narrative.
