What does the Bible say about God's sovereign choice in salvation?

Scripture affirms God's sovereign choice in salvation, emphasizing that He predestines people according to the 'good pleasure of His will' as seen in Ephesians 1:5. The doctrine of predestination highlights that before anything was done—good or evil—God had chosen certain individuals to be saved. This showcases His sovereignty, as described in Romans 9, where God asserts His right to have mercy on whom He wills. This idea challenges the notion of human merit, pointing instead to God's grace as the basis of salvation.
