Let me illustrate this subject by a few examples. We believe the assertions of Dr. Livingstone about the interior of Africa, although we have no means of verifying them by ocular observation, because we know that he has travelled there, and we are persuaded that he is a veracious witness. We accept the higher truths of astronomy, not because we have studied them, or are even able to appreciate the nature of the processes by which they have been arrived at, but because they are affirmed by persons who have afforded evidence that they possess a high order of knowledge on that subject. The same is true throughout the whole of the higher departments of science. We may call this an act of faith if we like, but it is also an act of our reason. The same thing is true throughout every department of human knowledge. It is astonishing how small a part of it is the result of our own personal observation. It follows therefore that the attempts which are so constantly made to separate faith and reason, and to erect an impassable wall between them, are suicidal alike both to faith and reason. As therefore we accept the affirmations of others on subjects within the limits of their own knowledge, although we ourselves are ignorant of the processes by which it has been arrived at, so we accept the affirmations of such a person as the Jesus of the Evangelists on those subjects on which he affirms that he possesses the fullest knowledge. But it will be objected that some of these assertions are made respecting high mysteries incomprehensible to the human intellect. Can we accept such truths?
