The Importance of Sabbath Observance

William Wilberforce had this to say about keeping the Sabbath day holy:

Oh what a blessed day is the Sabbath, which allows us a precious interval wherein to pause, to come out from the thickets of worldly concerns and give ourselves up to heavenly and spiritual concerns. Observation and my own experience have convinced me that there is a special blessing on a right employment of these intervals. Oh what a blessing is Sunday, interposed between the waves of worldly business like the divine path of the Israelites through Jordan. There is nothing in which I would recommend you to be more strictly conscientious than in keeping the Sabbath holy. By this I mean not only abstaining from all becoming sports and common business, but from consuming time in frivolous conversations, paying or receiving visits, which among relations often leads to a sad waste of this precious day. I can truly declare that to me the Sabbath has been invaluable.
