But you may say, “If inspiration gives _knowledge_, and these writers are inspired, then they do more than believe or think what they say about God, duty, and immortality. They _know_; and if they _know_, does not that mean that they are infallible?” No, knowledge is not infallibility. It is true that inspiration gives knowledge, while speculation only gives opinion. This is the reason why inspired men speak with authority, and philosophers without it. But knowledge, though it gives authority, does not give infallibility. A Frenchman _knows_ the French language; still he may make mistakes in speaking it. The man from California knows that country, but he may be mistaken about it. Thus, if these writers are not infallible, they may make mistakes; and if so, how are we to distinguish between their truth and their error? This is a fair question: let us try to answer it. Let us return to our former comparison of travellers and their guide. How are you to distinguish between your guide’s knowledge and his errors? Probably, when your guide begins to be uncertain as to the way, he will show his uncertainty in his behavior. He will become doubtful, hesitating, undecided; he will, by and by, supposing him honest, begin to express his uncertainty, and say, “I am not quite sure of this path.” It is just so with inspired writers. While their inspiration runs in a full tide, they speak confidently; they are distinct in their statements. Again, if your guide begins to speak of things outside of his province, he does not carry much authority. If Leatherstocking discusses Shakespeare, or the pilot begins to talk about politics, his opinions carry no weight except what is inherent to them. So when the writers of the Bible, leaving themes of religion and morals, describe natural objects, as the leviathan or behemoth, we give no more credit to their descriptions than we should to those of any other writer of their day. A question would arise here whether history was a subject of inspiration or not; that is, whether an inspired writer, when he comes to speak of historic facts, has any more authority than another. There may be some way by which past events might be presented by inspiration to the mind of one caught up by the spirit into another world. But the writers of the Old and New Testament are careless about dates and numbers, and do not seem to be made accurate by any special gift. I should, therefore, incline to the opinion that the historic books of the Bible have no authority except that of their reasonableness and conformity to what we might believe on other grounds. As fragments of history, coming from so remote a past, they are invaluable, when we treat them as simple, honest records of what was then believed or known. Take, for instance, the story of the deluge, and compare it with similar stories in other mythologies. We find it so corroborated by these, that we may believe that there is a basis of reality in it.
