I have already referred to the universality of the claims which Christianity makes upon us. Its aim is not to induce us to assume a certain character merely at certain specified times and in certain specified places, and to be content with that. On the contrary, its purpose is to induce us to do everything in one specified spirit, which shall shape, give sanctity and consecration to, the whole. Hence, it is never represented as working first on the outward habits of men, but on their hearts. It does not cleanse the outside of the cup or platter, leaving corruption within; but it first endeavours to establish purity within, and to give the purity which is within a force by which it shall work outwardly. The outward acts of the life are but the embodiments of the heart and will. Thus, whether we be scholars, or merchants, or preachers, or mechanics, or servants, we are to carry a soul, sanctified and governed by Christ, into all our occupations, even the commonest. Whether we pray or work, whether we be in the church or the shop, we are to be under the control of the one Christian spirit. Undoubtedly, there are some occupations in which it is difficult for Christians to engage, and some which they ought never to touch. But apart from these, the work of life is not an evil. There is no need to retire away from it into solitude as the only suitable sphere for the development of piety. A wise Christian looks upon it as a mode of spiritual culture. It depends upon the man himself, upon the guiding principle of his life, as to whether work shall degrade or raise him. Consider two or three points in illustration and proof of the truth I am endeavouring to enforce.
