Proofs for the Existence of God

In preceding articles we have sought to indicate something of the difference between a Reformed and an “evangelical” apologetics. Both Mr. White, the Reformed apologete, and Mr. ‘ Grey, the evangelical apologete, seek to defend the truth of Christianity. Both seek to get Mr. Black, the non-believer, to accept the truth about God and his creation. To both this is a matter of the greatest importance; they want to see Mr. Black redeemed from the “wrath of God” that rests upon him.

However, Mr. White and Mr. Grey have their internal disagreement about how best to win Mr. Black. And the reason for this disagreement is the fact that they disagree on the nature of that to which they would win Mr. Black. Their difference with respect to the method of apologetics is based on their difference with respect to theology, Mr. White holds to an unqualified while Mr. Grey holds to a qualified recognition of the sovereignty of God. Mr. Grey will recognize the sovereignty of God on condition that his own sovereignty be not altogether abolished.

Naturally there will be a difference between them on the requirement they will place before Mr. Black. iVI r. White wi ll require absolute surrender to God; Mr. Grey will be satisfied with a negotiated peace. Mr. White will require that Mr. Black henceforth interpret the whole of his life in terms of God; Mr. Grey will advise Mr. Black to interpret most of his life in terms of God.



1. Authority in Scripture

When Mr. Black objects against Mr. White that unconditional surrender to the authority of Scripture is irrational, then Mr. Grey nods approval and says that, of course, the “rational man” has a perfect right to test the credibility of Scripture by logic. When the Bible speaks of God’s sovereign election of some men to salvation this must mean something that fits in with his “rational nature.” When Mr. Black objects to Mr. White that unconditional surrender to Scripture is rationalistic, then Mr. Grey again nods approval and says that, of course, genuine human personality has a perfect right to test the content of Scripture by experience. When the Bible speaks of God by his counsel controlling whatsoever comes to pass, this must mean something that fits in with man’s freedom. God created man and gave man a share in his own freedom; men therefore participate in his being.

2. Authority in “General Revelation”

But what of natural or general revelation? Here surely there can be no difference, you say, between the requirements of Mr. White and Mr. Grey. Here there is no law and no promise; here there is only fact. How then can you speak of requirement at all? Here surely Mr. White can forget his “five points of Calvinism” and join Mr. Grey in taking Mr. Black through the picture gallery of this world, pointing” out its beauties to him so that with them he will spontaneously exclaim, “The whole chorus of nature raises one hymn to the praises of its Creator.”

3. Mr. White’s Silence

Let us think of Mr. White as trying hard to forget his “five points.” “Surely,” he says to himself, “there can be nothing wrong with joining Mr. Grey in showing” Mr. Black the wonders of God’s creation. We believe in the same God, do we not? Both of us want to show Mr. Black the facts of creation so that he will believe in God. When Mr. Black says: ‘I catch no meaning from all I have seen, and I pass on, quite as I came, confused and dismayed’ Mr. Grey and I can together take him by plane to the Mr. Wilson observatory so he may see the starry heavens above. Surely the source of knowledge for the natural sciences is the Book of Nature, which is given to everyone. Do not the Scriptures themselves teach that there is a light in nature, per se, which cannot be, and is not, transmitted through the spectacles of the Word? If this were not so, how could the Scriptures say of those who have only the light of nature that they are without excuse?”

4 . Mr. Grey’s Eloquence

So the three men, Mr. White, Mr. Grey and Mr. Black, go here and there and everywhere. Mr. White and Mr. Grey agree to pay each half of the expense. Mr. Black is their guest.

They go first to the Mr. Wilson observatory to see the starry skies above. “How wonderful, how grand!” exclaims Mr. Grey. To the marvels of the telescope they add those of the microscope. They circle the globe to see “the wonders of the world.” There is no end to the “exhibits” and Mr. Black shows signs of weariness. So they sit down on the beach. Will not Mr. Black now sign on the dotted line?

As they wait for the answer, Mr. Grey spies a watch someone has lost. Holding it in his hand he says to Mr. Black: “Look round the world: contemplate the whole and every part of it: you will find it to be nothing but one great machine, subdivided into an infinite number of lesser machines, which again admit of subdivisions, to a degree beyond that which human senses and faculties can trace and explain. All these various machines, and even their minute parts, are adjusted to each other with an accuracy, which ravishes into admiration all men, who have ever contemplated them. The curious adapting of means to ends, throughout all nature, resembles exactly, though it much exceeds, the productions of human contrivance; of human designs, thought, wisdom and intelligence. Since, therefore, the effects resemble each other, we are led to infer, by all the rules of analogy, that the causes also resemble; and that the Author of Nature is somewhat similar to the mind of man; though possessed of much larger faculties, proportioned to the grandeur of the work, which he has executed.

“Now, Mr. Black, I don’t want to put undue pressure on you. You know your own needs in your own business. But I think that as a rational being, you owe it to yourself to join the theistic party. Isn’t it highly probable that there is a God?

“I’m not now asking you to become a Christian. We take things one step at a time. I’m only speaking of the Book of Nature. Of course, if there is a God and if this God should have a Son and if this Son should also reveal himself, it is not likely to be more difficult for you to believe in him than it is now to believe in the Father. But just now I am only asking you to admit that there is a great accumulation of evidence of the sort that any scientists or philosopher must admit to be valid for the existence of a God back of and above this world. You see this watch. Isn’t it highly probable that a power higher than itself has made it? You know the purpose of a watch. Isn’t it highly probable that the wonderful contrivances of nature serve the purpose of a God? Looking back we are naturally led to a God who is the cause of this world; looking forward we think of a God who has a purpose with this world. So far as we can observe the course and constitution of the universe there is, I think, no difficulty on your own adopted principles, against belief in a God. “Thy not become a theist? You do want to be on the winning side, don’t you? Well, the Gallop poll of the universe indicates a tendency toward the final victory of theism.”

5. Mr. Black Politely Declines

When Mr. Grey had finished his obviously serious and eloquent plea, Mr. Black looked very thoughtful. He was clearly a gentleman. He disliked disappointing his two friends after all the generosity they had shown him. But he could not honestly see any basic difference between his own position and theirs. So he declined politely but resolutely to sign on the dotted line. He refused to be “converted” to theism. In substance he spoke as follows: “You speak of evidence of rationality and purpose in the universe. You would trace this rationality or purpose back to a rational being back of the universe who, you think, is likely to have a purpose with the universe. But who is back of your God to explain him in turn? By your own definition your God is not absolute or self;sufficient. You say that he probably exists; which means that you admit that probably he does not exist. But probability rests upon possibility. Now I think that any scientific person should come with an open mind to the observation of the facts of the universe. He ought to begin by assuming that any sort of fact may exist. And I was glad to observe that on this all important point you agree with me. Hence the only kind of God that either of us can believe in is one who may not exist. In other words, neither of us do or can believe in a God who cannot not exist. And it was just this sort of God, a God who is self-sufficient, and as such necessarily existent, that I thought you Christian theists believed in.”

By this time Mr. White was beg-inning to squirm. He was beginning to realize that he had sold out the God of his theology, the sovereign God of Scripture by his silent consent to the argument of Mr. Grey. Mr. Black was right, he felt at once. Either one presupposes God back of the ideas of possibility or one pre-supposes that the idea of possibility is back of God. Either one says with historic Reformed theology on the basis of Scripture that what God determines and only what God determines is possible, or one says with all non-Christian forms of thought that possibility surrounds God. But for the moment Mr. White was stupefIed. He could say nothing. So Mr Black simply drew the conclusion from what he had said in the following words:

“Since you in your effort to please me have accepted my basic assumption with respect to possibility and probability it follows that your God, granted he exists, is of no use whatsoever in explaining the universe. He himself needs in turn to be explained. Let us remember the story of the Indian philosopher and his elephant. It was never more applicable than to the present subject. If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world. In short, gentlemen, much as I dislike not to please you, what you offer is nothing better than what I already possess. Your God is himself surrounded by pure possibility or chance; in what way can he help me? And how could I be responsible to him? For you, as for me, all things ultimately end in the irrational.”

6. Mr. Grey Appeals to Logic

At this point Mr. Grey grew pale. In desperation he searched his arsenal for another argument that might convince Mr. Black. There was one that he had not used for some time. The arguments for God that he had so far used, he labeled a posteriori arguments. They ought, he had thought, to appeal to the “empirical” temper of the times. They started from human experience with causation and purpose and by analogy argued to the idea of a cause of and a purpose with the world as a whole. But Mr. Black had pointed out that if you start with the ideas of ca use and purpose as intelligible to man without God when these concepts apply to relations within the universe, then you cannot consistently say that you need God for the idea of cause or purpose when these concepts apply to the universe as a whole. So now Mr. Grey drew  out the drawer marked a posteriori argument. In public he called this the argument from finite to absolute being. “As finite creatures,” he said to Mr. Black, “we have the idea of absolute being. The idea of a finite being involves of necessity the idea of an absolute being. We have the notion of an absolute being; surely there must be a reality corresponding to our idea of such a being; if not all our ideas may be false. Surely we must hold that reality is ultimately rational and coherent and that our ideas participate in this rationality. If not how would science be possible?”

7. Mr. Black Again Declines

When Mr. Grey had thus delivered himself of this appeal to logic rather than to fact then Mr. White for a moment seemed to take courage. Was not this at least to get away from the idea of a God who probably exists? Surely the “incommunicable attributes of God,” of which he had been taught in his catechism classes, were all based upon and expressive of the idea of God as necessarily existing. But Mr. Black soon disillusioned him for the second time. Said he in answer to the argument from Mr. Grey, “Again I cannot see any basic difference between your position and mine. Of course, we must believe that reality is ultimately rational. And of course, we must hold that our minds participate in this rationality. But when you thus speak you thereby virtually assert that we must not believe in a God whose existence is independent of our human existence. A God whom we are to know must with us be a part of a rational system that is mutually accessible to and expressive of both. If God is necessary to you then you are also necessary to God. That is the only sort of God that is involved in your argument.”

8. Mr. Grey Testifies

“But Mr. Black, this is terrible, this is unbearable! We do want you to believe in God. I bear witness to his existence. I will give you a Bible. Please read it! It tells you of Jesus Christ and how you may be saved by his blood. I am born again and you can be born again too if you will only believe. Please do believe in God and be saved.”

9. Mr. White Hopes for the Best!

Meanwhile Mr. White took new courage. He realized that he had so far made a great mistake in keeping silent during the time that Mr. Grey had presented his arguments. The arguments for the existence of God taken from the ideas of cause and purpose as set forth by Mr. Grey had led to pure irrationalism and Chance. The argument about an absolute being as set forth by M r. Grey had led to pure rationalism and determinism. In both cases, Mr. Black had been quite right in saying that a God whose existence is problematic or a God who exists by the same necessity as does the universe is still an aspect of or simply the whole of the universe. But now he felt that perhaps Mr. Grey was right in simply witnessing to the existence of God. He thought that if the arguments used are not logically coercive they may at least be used as means with which to witness to unbelievers. And surely witnessing to God’s existence was always in order. But poor Mr. White was to be disillusioned again. For the witness bearing done by Mr. Grey was based on the assumption that the belief in God is a purely non-rational or even irrational matter.

10. Mr. Black Asks Some Pertinent Questions

Mr. Black’s reply to the words of Mr. Grey indicated this fact all too clearly. Said Mr. Black to Mr. Grey: “I greatly appreciate your evident concern for my eternal welfare. But there are two or three questions that I would like to have you answer. In the first place I would ask whether in thus witnessing to me you thereby admit that the arguments for the existence of God have no validity? Or rather do you not thereby admit that these arguments, if they prove anything, prove that God is finite and correlative to man and therefore that your position is not basically different from mine?”

Mr. Grey did not answer because he could not answer this question otherwise than by agreeing with Mr. Black.

“In the second place,” asked Mr. Black, “you are now witnessing to Christ as well as to God, to Christianity as well as to theism. I suppose your argument for Christianity would be similar in nature to your argument for theism would it not? You would argue that the Jesus of the New Testament is probably the Son of God and that he quite probably died for the sins of men. But now you witness to me about your Christ. And by witnessing instead of reasoning you seem to admit that there is no objective claim for the truth of what you hold with respect to Christ. Am I right in all this?”

Again Mr. Grey made no answer. The only answer he could consistently have given would be to agree with Mr. Black.

“In the third place,” asked Mr. Black, “you are now witnessing not only to Gael the Father, to Jesus Christ the Son, but also to the Holy Spirit. You say you are born again, that you know you are saved and that at present I am lost. Now if you have had an experience of some sort it would be unscientific for me to deny it. But if you want to witness to me about your experience you must make plain to me the nature of that experience. And to do that you must do so in terms of principles that I understand. Such principles must needs be accessible to all. Now if you make plain your experience to me in terms of principles that are plain to me as unregenerate then wherein is your regeneration unique? On the other hand, if you still maintain that your experience of regeneration is unique then can you say anything about it to me so that I may understand? And does not then your witness bearing appear to be wholly unintelligible and devoid of meaning? Thus again you cannot make any claim to the objective truth of your position.

“Summing up the whole matter, I would say in the first place, that your arguments for the existence of God have rightfully established me in my unbelief. They have shown that nothing can be said for the existence of a God who is actually the Creator and con troller of the world. I would say in the second place that using such arguments as you have used for the existence of God commits you to using similar arguments for the truth of Christianity with similar fatal results for your position. In both cases you first use intellectual argument upon principles that presuppose the justice of my unbelieving position. Then when it is pointed out to you that such is the case you turn to witnessing. But then your witnessing is in the nature of the case an activity that you yourself have virtually admitted to be wholly irrational and unintelligible.”

11. Mr. White Sees the Richness of His Faith

When Mr. Black had finished Mr. White was in a great distress. But it was this very distress that at last he saw the richness of his own faith. He made no pretense to having greater intellectual power than Mr. Grey. He greatly admired the real faith and courage of Mr, Grey. But he dared keep silence no longer. His silence had been sin, he knew. Mr. Black had completely discomfited Mr. Grey so that he had not another word to say. Mr. Black was about to leave them established rather than challenged in his unbelief. And all of that in spite of the best intentions and efforts of Mr. Grey, speaking for both of them. A sense of urgent responsibility to· make known the claims of the sovereign God pressed upon him. He now saw clearly first that the arguments. for the existence of God as conducted by Mr. Grey, are based on the assumption that the unbeliever is right with respect to the principles in terms of which he explains all things. These principles are: (a) that man is not a creature of God but rather is ultimate and as such must properly consider himself instead of God the final reference point in explaining all things; (b) that all other things beside him.. self are non-created but controlled by chance; and (c) that the power of logic that he possesses is the means by which he must determine what is possible or impossible in the universe of chance.

At last it dawned upon Mr. White that first to admit that the principles. of Mr. Black, the unbeliever, are right and then to seek to win him to the acceptance of the existence of God the Creator and judge of all men is. like first admitting’ that the United States had historically been a province of the Soviet Union but ought at the same time to be recognized as an independent and all-controlling political power.

In the second place, Mr. White now saw clearly that a false type of reasoning for the truth of God’s existence and for the truth of Christianity involves a false kind of witnessing following the existence of God and for the truth of Christianity. If one reasons for the existence of God and for the truth of Christianity on the assumption that Mr. Black’s principles of explanation are valid, then one must witness on the same assumption. One must then make plain to Mr. Black, in terms of principles which Mr. Black accepts, what it means to be born again. Mr. Black will then apply the principles of modern psychology of religion to Mr. Grey’s “testimony” with respect to his regeneration and show that it is something that naturally comes in the period of adolescence.

In the third place Mr. White now saw clearly that it was quite “proper” for Mr. Grey to use a method of reasoning and a method of witness bearing that is based upon the truth of anti-Christian and anti-theistic assumptions. Mr. Grey’s theology is Arminian or Lutheran. It is therefore based upon the idea that God is not wholly sovereign over man. It assumes that man’s responsibility implies a measure of autonomy of the sort that is the essence and foundation of the whole of Mr. Black’s thinking. It is therefore to be expected that Mr. Grey will assume that Mr. Black needs not to be challenged on his basic assumption with respect to his own assumed ultimacy or autonomy.

From now on Mr. White decided that, much as he enjoyed the company of Mr. Grey and much as he trusted his evident sincerity and basic devotion to the truth of God, yet he must go his own way in apologetics as he had, since the Reformation, gone his own way in theology. He made an appointment with Mr. Black to see him soon. He expressed to Mr. Grey his great love for him as a fellow believer, his great admiration for his fearless and persistent efforts to win men to an acceptance of truth as it is in Jesus. Then he confessed to Mr. Grey that his conscience had troubled him during the entire time of their travels with Mr. Black. He had started in good faith thinking that Mr. Grey’s efforts at argument and witnessing might win Mr. Black. He had therefore been quite willing, especially since Mr. Grey was through his constant efforts much more conversant with such things than he was, to be represented by Mr. Grey. But now he had at last come to realize that not only had the effort been utterly fruitless and self-frustrating but more than that it had been terribly dishonoring to God. How could the eternal I AM be pleased with being presented as being a god and as probably existing, as necessary for the explanation of some things but not of all things, as one who will be glad to recognize the ultimacy of his own creatures. Would the God who had in Paradise required of men implicit obedience now be satisfied with a claims and counter claims arrangement with his creatures?
