God’s deeds in the seven plagues are powerful and effective. The obvious reaction of earth’s population must be fear of God and (grudging) glorification and worship. This reaction is striking because it contrasts starkly with the nations’ current practice of worshipping the dragon (= Satan) and his beasts.
4 Who will not fear, O Lord, and glorify your name? For you alone are holy. All nations will come and worship you, for your righteous acts have been revealed.”
