What does it mean that God is a terrible God?

Describing God as 'terrible' is not an indictment of fear as we understand it, but a recognition of His unparalleled authority and holiness. The term correlates with the biblical understanding of God's majesty, where He commands creation and reveals His righteousness. Throughout Psalm 66, we see this characterized by His miraculous deeds, such as parting the Red Sea, which showcases His might and serves as a reminder of His ability to guide and protect His people. Acknowledging God's terribleness calls for reverence, leading us to worship and recognition of His foundational role in our salvation and the broader cosmic order.
