What does it mean that God is sovereign over all creation?

In the content of Revelation, God's sovereignty is profoundly emphasized as His decrees encompass both mercy and judgment. He is depicted as the King of Kings, ruling over all creation by the word of His power. This sovereignty assures believers that all things work according to His divine plan, which includes our salvation and the eventual restoration of creation through Christ. The assurance of God's control over both the natural and spiritual realms provides comfort to believers, affirming that nothing occurs outside of His eternal decree—a testament to His role as both sovereign and just.
