In this way Dr. Selbie prepares his students, not only to meet the intellectual difficulties of the future, but to stand fast in the ancient faith of their forefathers that the moral law is a fact of the universe. He helps them to be fighters as well as teachers. They are to fight the complacency of men, the false optimism of the world, the delusive tolerance of materialism. There is no need for them to preach hell fire and damnation, but throughout all their preaching, making it a real thing and a thing of the most pressing moment, must ring that just and inevitable word, Retribution. In a moral universe, selfishness involves, rightly and inevitably, suffering--suffering self-sown, self-determined, and self-merited. He is the last man in the world from whom one would expect such teaching to emanate. He seems, in his social moments, a scholar who is scarcely aware of humanity in his delicious pursuit of pure truth, a man who inhabits the faery realm of ideas, and drinks the milk of Paradise. But approach him on other ground and you find, though his serenity never deserts him, though he is always imperturbable and unassertive, that his interest in humanity and the practical problems of humanity is as vivid and consuming as that of any social reformer. There, in Oxford, among his books, and carrying on his duties as Principal of Mansfield College, Dr. Selbie, back from holidays spent in watching the great working world and listening to the teachers of that world, finds himself not alarmed, but anxious. The voice of religion, he feels, is not making itself heard, and the voices of churches are making only a discord. Men are going astray because they have no knowledge of their course, and the blind are falling into the ditch because they are led by the blind. How is this dangerous condition of things to be remedied? He replies, By the teachers. What we need at this hour above all other needs is the great teacher, one able to proclaim and explain the truths of religion, and filled with a high enthusiasm for his office. We need, he tells me, men who can restore to preaching its best authority. At the present time preaching has fallen to a low ebb because it is despised, and it is despised because it has lost the element of teaching. But let men recover their faith in the moral law, let them see that retribution is inevitable justice, let them realise that the life of man is a progress in spiritual comprehension, let them understand that existence is a great thing and not a mean thing, and they will feel again the compulsion to preach, and their preaching, founded on the moral law and inspired by faith in the teaching of Christ, will draw the world from the destructive negations of materialism, and wake it out of the fatal torpors of dull indifference.
