When commanded by the Jewish officials to quit invoking the name of Jesus Christ, Peter responded, "And there is salvation in no one else: for there is no other name under heaven that has been given among men, by which we must be saved" (Acts 4:12). Remember, Peter was a Jew, speaking to a group of Jews, claiming that there is no salvation for Jewish people - or anyone else - apart from faith in Jesus Christ.
