Why do Christians believe in sovereign grace?

Sovereign grace is a core tenet of Reformed theology that emphasizes God's absolute authority and control over salvation. It is grounded in Scripture, demonstrating that God chooses His people and applies the work of Christ to them according to His own purpose and will. Ephesians 1:4-5 illustrates that believers are chosen in Christ before the foundation of the world. This perspective alleviates the burden of works-based righteousness, affirming that salvation is wholly by grace through faith, ensuring that all glory goes to God alone.
