The Sabbath is necessary to promote the growth and strength of the moral principle. A man may render obedience to all the other precepts of the moral law; we may suppose them to be written on his heart; we may even suppose them to be so perfectly wrought into the temper and texture of his soul, that there is no deviation whatever. By his obedience he gives evidence of being in possession of the great principle of holiness. But this principle lives not by its own inherent vitality; it must be nourished and fed continually, or it withers and dies. However holy, however perfect the creature may be, he possesses no self-replenishing, self-renovating principle,--he must constantly resort to the great uncreated source for new supplies. The contrary supposition makes him independent of his Maker. Now the Sabbath is the season set apart and sanctified by God Almighty for this very purpose. It is the means of grace for keeping alive the great moral principle--the season when the creature goes right up to the Great Fountain, and drinks of its invigorating streams, whereby he comes forth rejoicing as a strong man to run a race. Hence we find that even when man was innocent; when he was in possession of the moral principle to perfection, still he was not left without a Sabbath season for the replenishing of his spiritual powers. If he needed a Sabbath then, much more does he need it now. For though he has been created anew in Christ Jesus,--the principle of holiness being thus re-implanted--yet has he a harder task to live holy to the Lord, inasmuch as there is "a law in his members warring against the law of his mind," "the flesh lusting against the spirit." Therefore he needs all the aid the Sabbath can bring to his soul. He needs "the restoring, the awakening day--the day of recovery and reformation--the day that brings him back to recollection, to seriousness, to penitence, to prayer." And when the last traces of sin shall have become obliterated, and man put in possession of all that perfection which pertains to the glorified state; still that perfection, we believe, will not be sustained by its own vitality, but will be preserved by means having a similarity to those employed on earth. For it is an everlasting Sabbath there, Heb. vi. 9. Yes, "----there's a nobler rest above, To which our lab'ring souls aspire, With ardent pangs of strong desire."
