What does the Bible say about God's call and redemption?

Isaiah 43 highlights God's sovereign initiative in calling His people, stating, 'I have redeemed you; I have called you by your name; you are mine.' This passage affirms the belief that redemption is not based on human effort but on God's grace. Furthermore, Romans 9 reinforces this concept by declaring that God has the right to show mercy to whom He chooses, emphasizing His sovereign authority over salvation. This understanding is foundational to the doctrine of election within sovereign grace theology, affirming that our hope rests solely in God's power and mercy rather than our own wills or actions.
