How do we know the doctrine of the fear of God is true?

The truth of fearing God is rooted in scripture, where Psalm 128 presents it as a critical aspect of a blessed life. This fear comes from a true knowledge of God, cultivated by the Holy Spirit, leading to genuine respect and reverence for God's authority. It is a fear that motivates worship, obedience, and a godly character. The fear of the Lord is foundational to the believer's faith and conduct, as evidenced in passages such as Hebrews 12:28, which calls us to serve God with reverence and godly fear.
