For by grace ye are saved through faith; and that not of yourselves: it is the gift of God: Not of works let any man should boast. ^{Ephesians 2:8-9}

There is nothing that man can do to earn salvation, it is a gift from God. Good works during your life do not bring salvation, only faith in Jesus Christ does that. We are saved for good works, not by good works. ^{Read Galatians 2:16}
