Happy would it be for each of us if we possessed more of this necessary serenity of mind, and if all our efforts, whether in connection with politics, science, social improvement, or our daily pursuits, were conducted in strict accordance with the revealed will of God! The latter is an essential without which we can neither enjoy individual happiness or experience national mercies. Past and present events most painfully demonstrate that a country may abound with wealth; that it may be fertile in its productions and possess great resources, and that the philanthropist may gaze with delight on its many noble Institutions; still, if its inhabitants daringly attempt to abrogate the Divine law of the Sabbath, a dark cloud will assuredly be seen that will cast a fearful gloom over the most highly-favoured land. “There is none like unto thee, O Lord; thou art great, and thy name is great in might. Who would not fear thee, O King of Nations! for to thee doth it appertain: forasmuch as among all the wise men of the nations, and in all their kingdoms, there is none like unto thee.” Jer. x. 6, 7. We will now proceed more in order with our subject, and, in doing so, it is necessary we should remember that we intend to confine ourselves almost exclusively to “the temporal advantages of the Sabbath to the labouring classes, and the consequent necessity of preserving its rest from all the encroachments of unnecessary labour.” This mode of procedure is in agreement with the contemplated object, viz. to procure from the sons of toil themselves an evidence of the mercy and love of God in commanding one _special_ day in seven to be devoted for rest from labour. To contemplate and enforce the importance of the Sabbath, in a spiritual view, is a duty which is being continually discharged by the Ministers of religion. 1. The Sabbath is indispensable, as a day of rest, both to body and mind; without it neither could be exerted with natural vigour.
