But to dismiss all further argument concerning the distinction between moral and positive duties, let it be admitted that the Sabbath is a positive institution in the very strictest sense; let it be admitted to be nothing more than an arbitrary appointment, having no foundation in the natural and primary relation of man to his Creator--it must nevertheless remain in force so long as that dispensation lasts to which it is peculiar. Hence it must still be in force; for the dispensation to which it belongs, is the dispensation of nature itself. While the dispensation of nature lasts, the day which God the Creator originally "blessed and sanctified," will continue to be sacred. It is utterly impossible that it should be otherwise; and therefore all speculations about its changeable nature, resulting from its being a positive appointment, are vain. Changeable and positive as were the carnal ordinances of the old economy, they were not changeable while that economy lasted, but were sacred throughout the whole of it. Changeable and positive as are the ordinances of Baptism and the Lord's Supper, they are not changeable while the dispensation to which they belong continues, but are sacredly binding until the dispensation ends. So of the Sabbath; yes, even of the very day originally appointed. Customary as it is with writers to draw the broad line of distinction between what they call the _moral_ and _positive_ parts of the institution, and whatever advantage it may have in _theory_, so far as _practice_ is concerned, nothing is gained by it. Indeed, with those who pretend to be guided by divine revelation, rather than by the unaided deductions of their own minds, it is always an unnecessary distinction. He whose heart is subdued to the will of God, will not be studious to inquire which of his commands are of a moral, and which of a positive nature. His inquiry will be simply this: "Lord, what wilt thou have me to do?" If God command, he will obey, let the nature of the command be what it will. Were man left to deduce the knowledge of his duty from the nature and fitness of things, without the aid of any light from above, God would not blame him if he should wholly neglect to practice those duties, which are commonly called positive. All that would be required of him in such case, would be the practice of those duties which are most obviously of the moral kind. But with the statute book of Almighty God in his hand, he stands on very different ground. He is thus brought under obligation--yea, under _moral_ obligation, to esteem ALL the divine precepts concerning _all things_, to be right. Psalm cxix. 128. SECTION IV. THE IMPORTANCE AND NECESSITY OF THE SABBATIC INSTITUTION.
