If the Pentateuch, or the Mosaic Law, had the power to save and give us eternal life…Jesus wouldn’t have had to come to earth to redeem mankind. Paul explains this further in Galatians 3:21 when he writes, “Is the Law, therefore, opposed to the promises of God? Absolutely not! For if a Law had been given that could impart life then righteousness would certainly have come by the Law.” No Law has the power to give eternal life…only the atoning death of Christ can do that….given to us by the grace of God.
