Why does God insist on faith? This is a question of some importance. It would be so easy for him to persuade us completely by reason alone. All he would have to do is make regular appearances and do a few tricks for the crowds. If he would make himself observable, we skeptical humans could grasp his reality more surely. So why doesn’t he do it?
As John Piper has noted, God’s primary motivation is his glory. He has made everything for his glory, to bring honor to his name. Perhaps, then, faith brings greater glory to God than a relationship based on tangible evidence of his existence. Even in relationships between humans, faith is an essential element. We don’t usually doubt one another’s existence—although some have claimed to have such doubts—but we do doubt one another in countless other ways. Perhaps I doubt my wife’s fidelity; I might hire a private investigator to follow her and see if she’s really doing what she says. Or maybe I doubt the sincerity of my boss’s praise. His boss gives him all the credit when I do all the work. He’s just trying to stay on my good side.
These doubts all involve things we can’t easily verify. They are intangible. My wife may be outwardly faithful but inwardly drifting further and further away from me. My private investigator won’t tell me that. And how can I determine my boss’s sincerity? Would it make his praise more sincere if his own efforts went unnoticed? Or is it my own envy that makes his sweet words bitter?
Let’s go a bit further. Is it really true that God could appear in such a way as to remove all doubt about himself? It seems to me that there are two answers to this question. The first is, yes, of course, God can overpower us with his awesome might. He can inspire such love in our hearts that we can’t help but yield to him. He can do such marvelous works on our behalf that we are compelled to acknowledge him. In short, he can make us trust him against our will and even against our reason. How does that serve his glory? What honor is there in being honored by automata—if indeed, it can be called honor?
The second answer comes from a more human perspective. If we assume that God does not overpower our will or reason, then we might have to say that God already appears in such a way as to remove all doubt about his existence. We only cling to doubt as a way of justifying our own rebellious indifference. For most humans throughout history, the existence of a Creator, a being who made everything, has been self-evident. It has not needed “scientific” justification. It was considered to be indisputable fact. It is only to the modern mind, educated by so-called Enlightenment thinking, that such doubts even occur.
The (r)evolutionary notion of human progress and perfectibility has taken such hold on the modern imagination that we no longer see a need for God. We have our big-bang theory to explain the universe (though, in fact, it only describes the process by which the universe came to be as it is without at all settling how it originated or what it all might mean). We have our theory of evolution to explain our own existence (though it, too, only describes a process without giving it meaning). We have come to believe that we can save ourselves, make heaven on earth, bring peace to the world, and shape our own destiny despite massive evidence to the contrary. How do we continue to hold on to these utopian dreams? What amazing faith we have in ourselves!
Who then is the greater fool—the one who believes in a God he cannot see but who provides ample evidence of his loving care or the one who puts his faith in fallen Man whose record of broken promises continues to grow? Our modern theories have taught us that nature is rife with selfish competition and opportunism, but an older view sees nature as the bounty of a loving God who provides even for the smallest of his creatures. “If God so clothes the grass in the fields which springs up today and is cast in the flames tomorrow, how much more will he clothe you, O you of little faith.” (See Matthew 6:30).
