The Christian concept of justification is that through faith in Jesus, the sinner is now regarded by God as guiltless. This means that by believing in Jesus and accepting him as Lord and Savior, a sinner is declared righteous and is no longer condemned for their sins. It is not through one's own efforts in keeping the law or through one's natural wisdom that a person is justified, but through faith in Jesus Christ. This is a gift from God, not something that can be earned or achieved through personal merit.
