Why do Christians believe in God’s sovereignty in salvation?

God's sovereignty in salvation is a core tenet in Reformed theology, emphasizing that God is the ultimate authority and initiator of salvation. Romans 8:28 states that 'all things work together for good to them that love God,' highlighting that nothing occurs outside of His sovereign will. The understanding of election and predestination as articulated in Ephesians 1:4-5 reinforces this perspective, showing that God chooses individuals for salvation not based on foreseen merit but according to His purpose and grace.
