It is also, besides being the recipient of impressions, and the possessor of needs and appetites, our instrument for working in the world. And so the exhortation of my text comes to include this, that all our activities done by means of brain and eye and tongue and hand and foot shall be consciously devoted to Him, and laid as a sacrifice upon His altar. That pervasive, universally diffused reference to God, in all the details of daily life, is the thing that Christian men and women need most of all to try to cultivate. 'Pray without ceasing,' says the Apostle. This exhortation can only be obeyed if our work is indeed worship, being done by God's help, for God's sake, in communion with God.
So, dear friends, sacrifice is the keynote--meaning thereby surrender, control, and stimulus of the corporeal frame, surrender to God, in regard to the impressions which we allow to be made upon our senses, to the indulgence which we grant to our appetites, and the satisfaction which we seek for our needs, and to the activities which we engage in by means of this wondrous instrument with which God has trusted us. These are the plain principles involved in the exhortation of my text. 'He that soweth to the flesh, shall of the flesh reap corruption.' 'I keep under my body, and bring it into subjection.' It is a good servant; it is a bad master.
II. Note, secondly, the relation between this priestly service and other kinds of worship.
I need only say a word about that. Paul is not meaning to depreciate the sacrificial ritual, from which he drew his emblem. But he is meaning to assert that the devotion of a life, manifested through bodily activity, is higher in its nature than the symbolical worship of any altar and of any sacrifice. And that falls in with prevailing tendencies in this day, which has laid such a firm hold on the principle that daily conduct is better than formal worship, that it has forgotten to ask the question whether the daily conduct is likely to be satisfactory if the formal worship is altogether neglected. I believe, as profoundly as any man can, that the true worship is distinguishable from and higher than the more sensuous forms of the Catholic or other sacramentarian churches, or the more simple of the Puritan and Nonconformist, or the altogether formless of the Quaker. I believe that the best worship is the manifold activities of daily life laid upon God's altar, so that the division between things secular and things sacred is to a large extent misleading and irrelevant. But at the same time I believe that you have very little chance of getting this diffused and all-pervasive reference of all a man's doings to God unless there are, all through his life, recurring with daily regularity, reservoirs of power, stations where he may rest, kneeling-places where the attitude of service is exchanged for the attitude of supplication; times of quiet communion with God which shall feed the worshipper's activities as the white snowfields on the high summits feed the brooks that sparkle by the way, and bring fertility wherever they run. So, dear brethren, remember that whilst life is the field of worship there must be the inward worship within the shrine if there is to be the outward service.
III. Lastly, note the equally comprehensive motive and ground of this all-inclusive directory for conduct.
'I beseech you, by the mercies of God.' That plural does not mean that the Apostle is extending his view over the whole wide field of the divine beneficence, but rather that he is contemplating the one all-inclusive mercy about which the former part of his letter has been eloquent--viz. the gift of Christ--and contemplating it in the manifoldness of the blessings which flow from it. The mercies of God which move a man to yield himself as a sacrifice are not the diffused beneficences of His providence, but the concentrated love that lies in the person and work of His Son.
