What does salvation by grace alone mean?

Salvation by grace alone is central to the gospel message, emphasizing that it is wholly an act of God's mercy rather than human effort. Ephesians 2:8-9 proclaims, '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 illustrates that salvation is unmerited and comes solely from God's altruistic love towards sinners. Recognizing that salvation does not hinge on our works frees believers from the burden of performance and instead invites them to rest in the gracious provision of Christ's sacrifice.
