What does the Bible say about salvation through faith?

The Bible reveals that salvation is entirely by grace through faith in Jesus Christ. As illustrated in the account of Rahab, she was spared not because of her actions alone but because she trusted in the God of Israel. Ephesians 2:8-9 affirms that it is by grace we are saved through faith, and this is not of ourselves; it is the gift of God, not of works, lest any man should boast. Rahab's faith led her to hide the spies, demonstrating that genuine faith naturally produces obedience,
which is evidence of one's relationship with God. Her salvation serves as a powerful reminder that it is faith—given by God—that grants us access to His grace and mercy, as seen in Romans 5:1-2.
