Sound doctrine is verified through Scripture and the transformative power of the Gospel in believers' lives.
The truth of sound doctrine is confirmed by its roots in Scripture and the historical teachings of the faith that was once delivered to the saints (Jude 1:3). The validity of sound doctrine is also recognized in its practical outcomes; it produces genuine faith that transforms lives, encouraging believers to walk in holiness and righteousness. As Paul emphasizes, grace is not an excuse for sin but empowers believers to live soberly, righteously, and godly, showing the truth of the doctrine in their everyday lives.
