The Sabbath is a golden clasp that unites God and His people. But the Sabbath command has been broken. God’s holy day has been desecrated. The Sabbath has been torn from its place by the man of sin, and a common working day has been exalted in its stead. A breach has been made in the law, and this breach is to be repaired. The true Sabbath is to be exalted to its rightful position as God’s rest day. In the fifty-eighth chapter of Isaiah is outlined the work which God’s people are to do. They are to magnify the law and make it honorable, to build up the old waste places, and to raise up the foundations of many generations. To those who do this work God says: “Thou shalt be called, The repairer of the breach, The restorer of paths to dwell in. If thou turn away thy foot from the Sabbath, from doing thy pleasure on My holy day; and call the Sabbath a delight, the holy of the Lord, honorable; and shalt honor Him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: then shalt thou delight thyself in the Lord; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord hath spoken it.” Verses 12-14.
The Sabbath question is to be the issue in the great final conflict in which all the world will act a part. Men have honored Satan’s principles above the principles that rule in the heavens. They have accepted the spurious sabbath, which Satan has exalted as the sign of his authority. But God has set His seal upon His royal requirement. Each sabbath institution bears the name of its author, an ineffaceable mark that shows the authority of each. It is our work to lead the people to understand this. We are to show them that it is of vital consequence whether they bear the mark of God’s kingdom or the mark of the kingdom of rebellion, for they acknowledge themselves subjects of the kingdom whose mark they bear. God has called us to uplift the standard of His downtrodden Sabbath. How important, then, that our example in Sabbathkeeping should be right.
In establishing new churches, ministers should give careful instruction as to the proper observance of the Sabbath. We must be guarded, lest the lax practices that prevail among Sundaykeepers shall be followed by those who profess to observe God’s holy rest day. The line of demarcation is to be made clear and distinct between those who bear the mark of God’s kingdom and those who bear the sign of the kingdom of rebellion.
Far more sacredness is attached to the Sabbath than is given it by many professed Sabbathkeepers. The Lord has been greatly dishonored by those who have not kept the Sabbath according to the commandment, either in the letter or in the spirit. He calls for a reform in the observance of the Sabbath.
