1. Ephesians 2:8-9
"For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast."
This foundational text establishes grace as the sole basis of salvation. Barnes explains that grace means "by mere favor. It is not by your own merit; it is not because you have any claim." Matthew Henry emphasizes: "The grace that saves is the free, undeserved goodness and favour of God; and he saves, not by the works of the law, but through faith in Christ Jesus." Gill describes grace comprehensively as "the free favour of God, to which salvation in all its branches is ascribed; as election, redemption, justification, pardon, adoption, regeneration, and eternal glory." The Pulpit Commentary clarifies that faith "indicates that attitude of men towards Christ in which it pleases God to save them." The Greek χάριτι (chariti) appears with the definite article, emphasizing God's specific, particular favor as salvation's source rather than any human merit (BibleHub Commentaries).
