Either what you believe is the truth or it is not the truth there is no neutrality

"The Christian believes in God; he believes that God will hold every one to account for the deeds done in the body; he expects a day of wrath and judgment. He acts in accordance with his belief. By trusting in Christ's finished work, and by giving evidence of that faith in his works in obedience to the injunction, 'if ye love me, keep my commandments,' the Christian shows to the world which postulate he accepts. But even if the self-styled skeptic or agnostic says nothing at all, it is perfectly clear that he believes there is no final judgment. He may protest in words that this is not true. He will say, 'It is not true that I believe there will be no judgment; I merely do not believe there will be a judgment. I do not know whether there will be a judgment or whether there will not. I am an agnostic, I do not know.' Now, either there is a God or there is not; either there is a final judgment or there is none. The skeptic must live by one or the other of these beliefs. He prays or he does not. But beyond this, if his protestation were sincere, he would have to admit that there was one chance in two that divine judgment would overtake him. If he knows nothing, and if there must be either a judgment or not a judgment, then so far as he knows the chances are even that there will be a judgment. And if a man really believed in the possibility, not to say the probability, of a judgment of God's wrath on sin, he would not adopt the attitude of indifference characteristic of self-styled agnostics. Their indifference is clear evidence that they believe that they are safe, that no judgment awaits them. Their life and action show what they believe. In this case, actions speak louder than words. Hence, whether one wish it or no, one is forced to adopt this or that theory. And there is no sense in denying in words the regulative principle which controls the life." - Gordon H. Clark, A Christian Philosophy of Education, Pg. 35, 36


Clark is known for his clarity in what he writes. Here however a man might read into his paragraph what is not there. Clark is not suggesting that works become our assurance or at all does works become our focus. He is simply saying that works follow faith. What a man believes does have some effect on what he does. However, of course not all the time. A Christian still sins even though he believes the truth. A man's worldview will effect his living (this is generally true).
