A very sharp test for us all lies in these thoughts. This change of the centre of interest from earth to heaven is the uniform effect of faith. What, then, of us? On Sundays we profess to seek for a city; but what about the week, from Monday morning to Saturday night? What difference does our faith make in the current of our lives? How far are they unlike--I do not mean externally and in occupations, but in principle--the lives of men who 'have no hope'? Are you living for other objects than theirs? Are you nurturing other hopes in your hearts, as a man may guard a little spark of fire with both his hands, to light him amid the darkness and the howling storm? Do you care to detach yourself from the world? or are you really 'men of this world, which have their portion in this life,' even while Christians by profession? A question which I have no right to ask, and no power to answer but for myself; a question which it concerns your souls to ask and to answer very definitely for yourselves. There is no need to preach an exaggerated and impossible abstinence from work and enjoyment in the world where God has put us, or to set up a standard 'too high for mortal life beneath the sky.' Whatever call there may have sometimes been to protest against a false asceticism, and withdrawing from active life for the sake of one's personal salvation, times are changed now. What we want to-day is: 'Come ye out and be ye separate, and touch not the unclean thing.' In my conscience I believe that multitudes are having the very heart of the Christian life eaten out by absorption in earthly pursuits and loves, and by the effacing of all distinction in outward life, in occupation, in recreation, in tastes and habits, between people who call themselves Christians, and people who do not care at all whether there is another world or not. There can be but little strength in our faith if it does not compel us to separation. If it has any power to do anything at all, it will certainly do that. If we are naturalised as citizens there, we cannot help being aliens here. 'Abraham,' says the New Testament, 'dwelt in tabernacles, _for_ he looked for a city.' Just so! The tent life will always be the natural one for those who feel that their mother-country is beyond the stars. We should be like the wandering Swiss, who hear in a strange land the rude, old melody that used to echo among the Alpine pastures. The sweet, sad tones kindle home-sickness that will not let them rest. No matter where they are, or what they are doing, no matter what honour they have carved out for themselves with their swords, they throw off the livery of the alien king which they have worn, and turning their backs upon pomp and courts, seek the free air of the mountains, and find home better than a place by a foreign throne. Let us esteem the reproach of Christ greater riches than the treasures of Egypt, and go forth to Him without the camp, for here have we no continuing city.
