It is highly significant that after the six days of creation comes the day of rest so that the first day of the world's history is a day on which God rested. Clearly God was not in need of a rest but he refrained from creating anything on that day so giving us a pattern for the future. There is to be a pattern in our lives. We work and we rest from work, we rest and we work. Christians differ on how that works out in practice but I would take the view that the Saturday Sabbath existed from Adam until the close of the Old Testament era when Christ stayed in the grave until he rose on the first day of the week at the beginning of the New Testament era. Christians should keep one day in seven, the first day of the week, different to the others, set apart to God and to his worship. We never do that perfectly but we should seek to keep the day to him, nevertheless.
