How do we know that faith in Jesus is our means of justification?

The doctrine of justification by faith is central to the teachings of the New Testament. Paul clearly states in Galatians 2:16 that 'a man is not justified by the works of the law, but by the faith of Jesus Christ.' This means that our righteousness comes solely from Christ’s obedience and sacrifice, not from our own efforts to adhere to the law. As further emphasized in Romans 3:27, all boasting about personal accomplishments before God is excluded because our salvation is based on faith in Him alone, affirming the complete work done by Christ.
