How does grace alone play a role in salvation?

Ephesians 2:8-9 clearly states that 'For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.' This reflects the Reformed understanding that our salvation is entirely dependent on God's grace alone. This means that no amount of human effort or good works can contribute to salvation, as it is a divine gift. Emphasizing grace alone highlights God's mercy and love in choosing to save unworthy sinners, and it assures believers of their eternal security since their salvation rests solely on Christ’s finished work.
