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).

What worldview is best and true?

"But now we have fallen into an 'ocean of arguments' no less deep and wide than Plato's Parmenides. Suppose the child, the human being, is an evolutionary product, simply a more complicated animal, without a soul, especially without an immortal soul. The late Supreme Court Justice, Oliver Wendell Holmes, said, 'I can see no reason for attributing to man a significant difference in kind from that which belongs to a baboon or to a grain of sand. . . . I wonder if cosmically an idea is any more important than the bowels.' Bertrand Russell's famous passage, quoted in chapter three, builds life and therefore education 'only on the firm foundation and unyielding despair.' The end of man is a doom, pitiless and dark. All the labor of the ages is destined to extinction and must inevitably be buried beneath the debris of a universe in ruins. Suppose on the other hand that God created man in His own image and breathed into him the breath of life, with the result that those redeemed by Christ shall glorify God and enjoy him forever.
Teachers teach pupils. But whereas a teacher with the first view of what a pupil is teaches despair along with arithmetic or social consciousness; the teacher with the second view teaches hope.
In these two views, naturalism and theism, are interwined all the strands of philosophy. Even the question whether the government should control education for its own ends and ban God from the schools, or whether the church, home, or private corporations should do the educating, depends on what man is. Once admit that the teacher teaches pupils, it is impossible to rule out any part of philosophy as irrelevant.
Among the considerations that have come under review, some mention has been made of the effect of government on education. Mention should also be made of the effect, or alleged effect, of education on government. Americans often speak of public education as if it were the main support of democracy. Without an educated populace all sorts of evils would proliferate, and the professional educators claim that unless legislatures appropriate almost unlimited amounts of tax money for the schools, the nation will shortly collapse. The fact of the matter is that with hundreds of billions already appropriated for public education, all sorts of evils have proliferated and the nation is already collapsing. A Justice of the United States Supreme Court was forced to resign in the 1960's because of suspicious financial arrangements. The 1970's and 1980's have seen a series of national scandals in all three branches of the government. No wonder America raises its crime rate faster than it inflates its money." -Gordon H. Clark, A Christian Philosophy of Education, Pg. 8-9
