How do we know God saves sinners by grace?

The doctrine of grace is foundational to understanding salvation in a Reformed context. As stated in 2 Timothy 1:9, God gave us grace before the foundation of the world, implying that His choice to save sinners is not based on any conditions met by us, but solely on His sovereign will. In the sermon, it is emphasized that God called Abraham from idolatry and set him apart, demonstrating His active role in salvation. Salvation is thus understood as an act of God’s grace, effectuated by His will and love for His elect, ensuring that all He intends to save will indeed come to Him.
