The Crusades were a magnificent revival. The Reformation was a revival. The Salvation Army movement is a revival. But the greatest revival of all times is even now upon us: it is a revival in the scientific circles of the race. Time was when science and religion were supposed to be at odds; to-day the intellectual phalanxes are sweeping Christward with an impetus that is sublime! Thinkers are finding in the large life of religion a motive power for their thought, their growth--a reason for their existence--a forecast of their destiny. We are beginning to realize the dynamic value of Belief. This revival is coming, not with shouts and noise, but with the quiet insistence of new ideas, of new facts--with the still voice of scientific announcement. The atheist is being overcome, not by emotion, but by evidence; the scoffer is being put down by cool logic. Hence the evangelist of to-day is more than a man who can popularly address a public audience, and by tales and tears arouse a weeping commotion. The evangelist is a man of intellect and prayer, who can preach the gospel to a scientific age, and to a thinking coterie--a coterie of college men and mechanics, of society women and servant-girls, of poets and of mine-diggers, of convicts and of reformers. To-day calls for the utmost intellectual resources of the teacher of the truth, for a great imagination, great style, great sympathy with men, large learning, and unceasing prayer! 3. His rule is over social ideals. He must be a man of social insight. The social spirit is abroad in the world, but it is woefully erratic and misguided. Any one thinks he can be an altruist. Why not? Take a class in a college settlement, make some bibs for a day nursery, give tramps a C.O.S. card, with one's compliments, and attend about six lectures a year on Philanthropy--the lectures very good indeed. One is then a full-fledged altruist, _n'est-ce pas_? The philanthropy of to-day has a bewildering iridescence of aspect. Each present impulse is reformatory. Correction, like a centipede, shows a hundred legs and wants to run upon them all. Much of the so-called philanthropy is not well balanced and is run by cranks. Cranks attach themselves to any social movement, as a shaggy gown will gather burrs. It is not all of philanthropy to classify degenerates, titter at ignorance, and to go a-peeping through the slums! We have not yet realized the fulness of redemption. Of what avail is it to save one street-Arab, or one Chinaman, if a million Arabs and Chinamen remain unsaved? Redemption is a race-savior: it seizes not only the individual, but his environment, his friends, and his future state.
