I do not say that sickness confers these benefits on all to whom it comes. Alas, I can say nothing of the kind! Myriads are yearly laid low by illness, and restored to health, who evidently learn no lesson from their sick beds, and return again to the world. Myriads are yearly passing through sickness to the grave, and yet receiving no more spiritual impression from it than the beasts that perish. While they live they have no feeling, and when they die there are "no bands in their death." (Psalm lxxiii. 4.) These are awful things to say. But they are true. The degree of deadness to which man's heart and conscience may attain, is a depth which I cannot pretend to fathom. But does sickness confer the benefits of which I have been speaking on only a few? I will allow nothing of the kind. I believe that in very many cases sickness produces impressions more or less akin to those of which I have just been speaking. I believe that in many minds sickness is God's "day of visitation," and that feelings are continually aroused on a sick bed which, if improved, might, by God's grace, result in salvation. I believe that in heathen lands sickness often paves the way for the missionary, and makes the poor idolater lend a willing ear to the glad tidings of the Gospel. I believe that in our own land sickness is one of the greatest aids to the minister of the Gospel, and that sermons and counsels are often brought home in the day of disease which we have neglected in the day of health. I believe that sickness is one of God's most important subordinate instruments in the saving of men, and that though the feelings it calls forth are often temporary, it is also often a means whereby the Spirit works effectually on the heart. In short, I believe firmly that the sickness of men's bodies has often led, in God's wonderful providence, to the salvation of men's souls. I leave this branch of my subject here. It needs no further remark. If sickness can do the things of which I have been speaking (and who will gainsay it?), if sickness in a wicked world can help to make men think of God and their souls, then sickness confers benefits on mankind. We have no right to murmur at sickness, and repine at its presence in the world. We ought rather to thank God for it. It is God's witness. It is the soul's adviser. It is an awakener to the conscience. It is a purifier to the heart. Surely I have a right to tell you that sickness is a blessing and not a curse,--a help and not an injury,--a gain and not a loss,--a friend and not a foe to mankind. So long as we have a world wherein there is sin, it is a mercy that it is a world wherein there is sickness. III. The third and last point which I propose to consider, is _the special duties which the prevalence of sickness entails on each one of ourselves_.
