How do we know God is sovereign over all creation?

God's sovereignty is a foundational doctrine in Reformed theology, affirming that He reigns supreme over all creation and governs the affairs of humanity according to His divine purpose. Isaiah 40 emphasizes God's incomparable nature and His authority over all nations and their rulers. When we look at passages such as Matthew 21, we see God's sovereign plan unfolding through history as He directs the actions of people toward His predetermined ends. This sovereignty brings comfort to believers, knowing that all things work together for the good of those who love Him (Romans 8:28).
