What does the Bible say about fearing God and keeping His commandments?

The scripture teaches that fearing God and keeping His commandments encompasses the entire duty of humanity. In Ecclesiastes 12:13, Solomon concludes that the essence of life is to fear God and obey His commands. This aligns with 2 John 4, where the importance of walking in truth and obeying God's commandments is highlighted. True fear of God compels believers to live in a manner that reflects His holiness and righteousness, recognizing that all accomplishments and victories are ordained by Him, not by human effort.
