Revenant fear is a good thing and it guides to wisdom so that one does not present themself arrogantly before God. He is not only our Heavenly Father, He is our King, the Creator of all things and is worthy of praise and glory; not our arrogance or self righteous behavior. Deuteronomy 31:6, Joshua 1:9, Isaiah 41:10, 40:28-31, 27:1, 23, Proverbs 1:27, Psalm 1:10, 4:8, 23.
