Romans 10:3 and 4: Many people think they can merit Eternal Life by being religious and pious. But all of our very best works are but refuse to Almighty God (Isaiah 64:6 and Romans 3:10-12). We must get the religious to see that their religion has no value at all to God and actually hinders our Salvation (Philippians 3:4-9).
Romans 10:5: God gave Israel a Law through Moses. This Law was never intended to save anyone. The Law made all guilty (Romans 3:19 and 20). The Law pointed out our desperate need of a Savior (Galatians 3:23-25).
