We know grace alone saves us because the Bible emphasizes that salvation is a gift, not based on our works, but on the finished work of Christ.
The doctrine of salvation by grace alone is rooted in the biblical teaching that human effort cannot achieve reconciliation with God. Ephesians 2:8-9 asserts that we are saved by grace through faith, and this is not of ourselves; it is the gift of God. Additionally, the completed work of Christ on the cross is the foundation of our salvation. This signifies that our good deeds, however well-intentioned, cannot contribute to our standing before God. Understanding this truth allows us to rest in the assurance that salvation is entirely dependent on God's grace, not on our merit.
