Knowledge of God’s power and coming judgment should rightly terrify God’s enemies. The Canaanites were frightened because they knew something about God: they knew that he is coming to judge them (Joshua 2:9–11).
Elsewhere in the Bible, we also see how God’s enemies quake in terror and melt in fear when they come to an understanding of God’s power and hatred of sin. For example, in the Gospel According to Mark, the demons cried out when they saw Jesus, fearful that he had come to destroy them (Mark 1:24). The letter of James tells us that the devils shudder when they think of the one true God (James 2:10). They know his power, they are terrified of him. Revelation 6:12–17 ends with the kings of the earth and the powerful rulers of the world hiding themselves in caves and among rocks, calling out for the mountains to fall upon them in order to hide them from the wrath of the Lamb.
A knowledge of God’s power and coming judgment is a knowledge that causes his enemies to melt in fear.
