The first thing we must do, in view of all that we have seen together, is agree to grasp the Bible as our full and final authority in all matters of revelation. Having seen that we cannot get anywhere without the Bible, then the obvious thing to do is to say, 'Very well, I accept the Bible. I don't know anything apart from it. I have no knowledge of God apart from what the Bible tells me. I may theorize, and other people may do the same thing, but I really do not know anything apart from what I find in this book.' So the first decision we must make is that we are going to be, as John Wesley put it, men and women 'of one book'. Here is my only source, my only authority.
But I want to underline this and even emphasise it still further. I must submit myself entirely to the Bible, and that will mean certain things. First, I start by telling myself that when I come to read the Bible and its doctrines, I am entering into a realm that is beyond the reach of my understanding. By definition, I shall be dealing with things that are beyond my power to grasp. The very idea of revelation , in and of itself, I suggest to you, must carry that implication. We are going to try and know God and study the doctrines concerning Him, and it must be the case that these truths are beyond our understanding. If I could understand God, I would be equal with Him. If my mind were able to apprehend and to span the truth about God then it would mean that my mind is equal to the mind of God, and that, of course, is altogether wrong.
For instance, in our next lecture we hope to be dealing with the doctrine of the Trinity. Now there by definition is a doctrine that no one can possibly understand, but let us agree to say that before we come to the doctrine. Let nobody think, however, that this means committing intellectual suicide when we take up the Bible. It simply means that we recognize that there is a limit to reason. We agree with the great French mathematician and philosopher, Pascal, that the supreme achievement of reason is to teach that there is an end and limit to reason. Our reason takes us so far and then we enter into the realm of revelation, where God is graciously pleased to manifest Himself to us.
But now I am anxious to emphasise the second point. It means that we must accept truths where we cannot understand them and fully explain them. Not only must we agree that we cannot, of necessity, understand everything, but also, when we come up against particular doctrines and truths, we must accept them if they are in he Bible, irrespective of the fact that we can or cannot understand them. Now I rather like to think of faith in that way. I am not sure but that the best definition of faith we can ever arrive at is this: faith means that men and women decide quite deliberately to be content only with what they have in the Bible, and that they stop asking questions."
