God's grace is considered sovereign because it is unmerited favor bestowed upon individuals according to His will, as stated in Romans 9:15-16.
The doctrine of sovereign grace emphasizes that God's choice to show mercy is not based on our actions or merit but solely on His divine will. Romans 9:15-16 makes it clear when Paul states, 'I will have mercy on whom I will have mercy.' This assertion underlines the unearned nature of God's grace, which is a cornerstone of Reformed theology. It illustrates that all spiritual blessings come from God's gracious decision to call certain individuals to salvation, affirming that our standing before God is entirely due to His sovereign grace and not our own works.
