How do we know that we are saved by grace?

The doctrine of salvation by grace is central to Reformed theology and is clearly articulated in Ephesians 2:8, where Paul states that salvation is not a result of our own efforts or decisions, but a gift from God. This grace is a manifestation of God's love and mercy, as He quickens those who were spiritually dead. The assurance of salvation resides not in our actions but in the work of Christ on our behalf—His death and resurrection—which aligns perfectly with the Reformed emphasis on sovereign grace. God's initiative in salvation underscores the belief that, without His granting of grace, none would be able to believe or receive life. Thus, grace is absolutely essential to the believer's assurance and experience of salvation.
