Through faith in Christ (v. 22a). Faith is only as good as its object. All people trust something, if only themselves, but the Christian trusts Christ. Law righteousness is a reward for works. Gospel righteousness is a gift through faith. Many people say, “I trust in God!” But this is not what saves us. It is personal, individual faith in Jesus Christ that saves and justifies the lost sinner. Even the demons from hell believe in God and tremble, yet this does not save them (James 2:19).
