Lastly, let me remark how dangerous their state is who are content to take the truths of the Gospel on trust, without caring whether or not those truths are realized in their own heart and conduct. Such men, when assailed by ridicule and sophistry, are likely to fall; they have no root in themselves; and let them be quite sure, that should they fall away from the faith, it will be a slight thing at the last day to plead that subtle arguments were used against them, that they were altogether unprepared and ignorant, and that their seducers prevailed over them by the display of some little cleverness and human knowledge. The inward witness to the truth lodged in our hearts is a match for the most learned infidel or sceptic that ever lived: though, to tell the truth, such men are generally very shallow and weak, as well as wicked; generally know only a little, pervert what they know, assume false principles, and distort or suppress facts: but were they as accomplished as the very author of evil, the humblest Christian, armed with sling and stone, and supported by God's unseen might, is, as far as his own faith is concerned, a match for them. And, on the other hand, the most acute of reasoners and most profound of thinkers, the most instructed in earthly knowledge, is nothing, except he has also within him the presence of the Spirit of truth. Human knowledge, though of great power when joined to a pure and humble faith, is of no power when opposed to it, and, after ail, for the comfort of the individual Christian, it is of little value. May we, then, all grow in heavenly knowledge, and, with that end, labour to improve what is already given us, be it more or be it less, knowing that "he that is faithful in little is faithful also in much," and that "to him that hath, more shall be given."
