What does the Bible say about God's supremacy?

Scripture emphasizes the absolute supremacy of God, as seen in Psalm 115:3, which states, 'But our God is in the heavens; He does all that He pleases.' This affirms His authority over creation and His sovereign control over all events. God's supremacy means that He is not only the Creator but the sustainer of all things, and He governs the universe according to His eternal purpose. His will is not subject to the whims of humanity, and He can use even the actions of sinful men to accomplish His divine plans, as illustrated through the events surrounding Christ's crucifixion.
