How do we know that God's sovereignty is essential in salvation?

The sovereignty of God is a foundational truth in understanding salvation, as it underscores that God, in His divine prerogative, selects those who will be saved according to His purpose and will. Romans 9:16 states, "So then it is not of him that willeth, nor of him that runneth, but of God that shows mercy." This verse highlights that it is not through human effort or desire, but through God's unilateral decision that individuals are called into His kingdom. This doctrine serves to reaffirm the assurance that salvation is secure, as it relies solely on God’s actions rather than human actions, ensuring that none can boast in their own abilities but must trust in the completed work of Christ. Understanding this sovereignty leads to a more profound appreciation of God’s grace, as it is entirely His mercy that grants new life to the spiritually dead.
