What does the Bible say about God's sovereignty over salvation?

In Romans 9, Paul outlines the sovereignty of God in election, emphasizing that salvation is not based on human effort or merit, but on God's mercy and divine will. He explains that God chooses vessels of mercy from the same lump of clay that also produces vessels of wrath. This demonstrates that God's justice and grace coexist perfectly within His nature. It is ultimately God who decides to whom He gives saving grace, and this truth calls us to submit to His sovereign authority without objection.
