Is the Jewish Passover service a picture of the program of grace?
Yes. The Jewish Passover service is described as a beautiful picture of the whole program of grace, and many Jewish feast days are beautiful pictures of the doctrine of grace. However, keeping those feast celebrations cannot save anyone; Jews must also come by grace, not works.
Les explains that while the Passover service and many Jewish feast days are beautiful pictures of the whole program of grace and the doctrine of grace, Jewish people are not saved by keeping those ceremonies. He emphasizes that Jews and Gentiles are all unworthy and without hope, and a Jew must be saved the same way Gentiles are today—by the gospel of grace, dropping the works religion of Judaism. If it is by grace, it is no more of works.
