How does one's faith relate to salvation?

In the context of biblical salvation, faith is not a work that earns favor with God but a gift and response to His grace. Zacchaeus did not perform good works to obtain salvation; rather, his act of hospitably receiving Jesus into his home was a manifestation of the faith that God had granted him. Ephesians 2:8-9 clarifies 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 underscores that true faith results from God's initiative to save, illustrating how a person's faith is validated through their actions as evidence of a transformed heart.
