The doctrine of faith is validated through the authentic transformation and testimony of believers, especially evident in Paul's life.
The truth of the doctrine of faith is evidenced by the radical changes it produces in believers' lives. Paul, once a vehement persecutor of Christians, was transformed into a fervent preacher of the gospel. This transformation serves as a powerful testament to the efficacy of the faith he now proclaims. Moreover, the Scriptures affirm that genuine faith results in a life characterized by love for Christ and His people, thus demonstrating its divine origin and truth. Authentic faith is not merely an assent to doctrines but a living faith that actively influences the believer's life and actions.
