How does grace relate to salvation according to the Bible?

Grace plays an essential role in salvation, demonstrated in Ephesians 2:8-9, where it states that we are saved by grace through faith, and that faith itself is a gift from God. This underscores that salvation is not something we can earn or initiate but is entirely dependent on God's grace and His work in our lives. The concept emphasizes our helpless condition and the necessity of divine intervention for anyone to come to faith and ultimately be saved. It dismisses boasting in human effort and attributes salvation solely to God’s mercy.
