This film is a detailed study of the bible about the concept of the Sabbath.
As the Sabbath cannot be full understood without a good understanding of the scriptures this film is also a study on the different covenants in the Bible, such as the Abrahamic and the Mosaic. This is a study for every Christian, not just people concerned about the Sabbath, as it is the story of the Gospel. I hope it will help you understand the plan of God more and praise Him for His goodness to us.
