I must here consider for a moment one of the gravest questions which arises in many minds about the progress of Christianity. Granted that its speed was rapid at the first, why has it ever stagnated since? If it be the great remedy for human woes, and the great prompter of human virtue and morality, why did not its Divine Author, if Divine He be, ordain that it should at once find its way everywhere, and should never fail anywhere? I am ready to admit the gravity of the question. I doubt if there be any greater mystery connected with the faith of Christ. It was objected to that faith by Lord Herbert of Cherbury, perhaps the most eminent of the deists of the last century, and it has tried many a believing, as well as many a doubting spirit, since. We naturally feel, that a religion meant to save all men ought to be made known to all men. In the few words I can say on it now, I do not pretend to clear up all the mystery. I cannot clear up all the mystery of God's actions or of God's will. I would only remind you first, that this is at all events but one specimen of the working of that general law, which seems to rule in creation, in Providence, and in grace. The analogy between the development of nature and the development of revelation was ably traced in the lecture of one who preceded me some fortnight or three weeks back. It certainly seems the principle of the Divine action, that all things should rise up into maturity by steady gradual progress and growth. So the infancy of mankind was left in the glimmer of twilight; then there was a dawning light in the ages of the patriarchs and the prophets, till the day broke full upon the world in the coming into it of Jesus Christ. By the same kind of gradual working, that day-spring from on high has extended its brightness first to one land and then to another. It is no more marvellous that China and India and Central Africa should not yet have seen it all, than that for thousands of years of man's past history, the whole human race, except at most a very small portion of it, should have known nothing of Christ or even of God. There has been an infancy of man, as there has been an infancy of the Universe; and we may well believe, that there may have been a preparation for Christ's coming, and elsewhere a preparation for the knowledge of His coming, corresponding with the preparation through countless ages past for the habitation of man upon the earth.
