Why is grace central to understanding salvation?

Grace is foundational in Reformed theology, as it emphasizes that salvation is an act of God’s unmerited favor towards sinners. Without grace, there would be no access to God, and humans would remain under judgment. The grace of God is seen vividly in the sending of Christ to bear the sins of His people, demonstrating that salvation is solely a work of God (Ephesians 2:8-9). This grace is freely given, and understanding it reshapes our entire relationship with God, granting us assurance and hope.
