How do we know that salvation is based on faith and not works?

The doctrine of salvation by faith alone is foundational to Reformed theology, emphasizing that salvation is purely a work of God's grace. Ephesians 2:8-9 highlights that we are saved by grace through faith, which is a gift from God, distinctly apart from our works to prevent any boasting on our part. Additionally, Scripture teaches that the evidences of our faith, such as good works, should flow naturally from a transformed heart as a result of being saved, not as a means to attain salvation.
