But in the case of races like the Karens of Burma, the Pariahs and other low castes of India, and the negro slaves of the West Indies, Christianity finds human beings suffering from special disabilities, a lowly people, shut out, by the selfishness of those above them, from all the ordinary chances of bettering their lot, ill-used, oppressed, enslaved, kept in unlettered ignorance, deprived of all that makes life worth living. When the Gospel messenger speaks to them hopefully of a better state of things, and holds out a helping hand, it is evident, even to their dark minds, that this is their one chance of improvement, both in temporal and eternal things. They have everything to gain and almost nothing to lose by embracing the Gospel, and the consequence is that the success of the Gospel amongst such races is usually rapid. Another class of races there is, consisting of tribes wild and barbarous, beyond the confines of civilisation, and from time immemorial left to themselves, whose state of primitive savagery precludes the possibility of any elaborate form of religion, quite unlettered, and without a written language. Such are many of the races of the interior of Africa, many of the hill-tribes of Asia, and the inhabitants of the groups of islands in Polynesia. Here, again, are found the conditions generally favourable for a rapid ingathering, notwithstanding their extreme barbarism and coarse brutality at first, amounting sometimes to cannibalism. For even the savage is conscious before long that he has something to gain by adopting the ways of civilisation. Where mission work has been conducted with perseverance in such countries it has always been successful. When we have fully recognised the mighty power of the Holy Spirit, to whose gracious influences we are indebted for _all_ Gospel success, and when we have said all we have to say about different methods and men, the student of missions will still feel that he has not fully accounted for the marked diversity in the successes; he must also take account of the social and economic conditions of the different races, when the Gospel addresses them, and the hold their own religions generally have upon their minds. For the Gospel is like every other force in the universe, whether moral or physical, in this, that it always proceeds with most energy along the track of the least resistance; and he will find, if he carefully studies the matter, that the difficulties arising from social disabilities, and from a low state of civilisation, are not the greatest possible hindrances to the Gospel. In the approaching revival of missionary activity and enthusiasm these questions are sure to receive more careful attention; and when these problems come to be considered, Burma with its different races will contribute not a few interesting facts and experiences.
