How do we know grace is central to salvation?

The doctrine of grace is foundational in Reformed theology, especially as highlighted in Ephesians 2:8-9, which teaches that our salvation is entirely by grace through faith. This means that we do not earn our salvation through our deeds or efforts; rather, it is a free gift from God. The notion that we are saved by grace alone underscores God’s sovereignty and mercy, showing that even our faith is divinely initiated. This understanding of grace leads believers to acknowledge that all glory belongs to God and emphasizes our complete dependence on His kindness and love.
