Faith is a tricky subject. How much of an open mind can one have before his brain falls out? How closed minded can one afford to be before truth gives up knocking? The Bible says a lot on the topic of faith.
There are three approaches to the human mind. The first is that it is everything. Man, be it the dominant culture, the prevailing authorities or academics, or the individual, is the ultimate authority on truth. What the selected authorities believe, that is what is true, no matter what the evidence.
The second is that the mind is nothing. We can know only one thing, and that is that we know nothing. Confidence is arrogance, and a closed mind is evil. There are no absolutes, and that is absolutely true.
The third is that the mind is neither everything, nor is it nothing. It was designed with a purpose, and it fulfills that purpose very well. Unfortunately, it still makes errors.
In the first scenario, man thinks too highly of himself. It refuses to acknowledge the fallibility of our own minds. The conclusions we draw, even when based on the evidence, can sometimes be wrong.
In the second scenario, man thinks too little of himself. The reasoning ability of man is undermined, and correct conclusions are rejected purely because they claim to be correct.
Only the third approach, the Biblical approach, fully acknowledges the capability of the human mind and accepts its flaws.
There are things in this world too complex for human beings to understand. The spiritual world is especially confounding. Our world tells us that strength, intelligence, and selfishness are good for survival, yet the Bible tells us these things are futile. Even the cruelest of unbelievers recognise some forms of morality that seem counterintuitive from a naturalistic perspective. Therefore, we are told that trust in the Lord, leaning not on our own understanding. At the same time, deception is common in this world. First impressions, intentional lies and even demonic influence are all commonplace. Therefore, we are instructed to test all things. Faith, therefore, is neither blind, nor purely seen. It is a healthy combination of trust and skepticism.
But most importantly, it is dependence upon that which is higher than ourselves. This is why the fear of the Lord is the beginning of wisdom. We will never be perfect in this world, but when we trust in the one who is perfect, He guides us into truth. This will offend those who stubbornly cling to falsehoods, as well as those who cling to the idea that it is foolish to cling to ideas, but it is indeed true.
Furthermore, it is stronger than any other worldview, as it accounts for human reason. Stubborn worldviews cling to sources that wouldn't allow for such stubbornness. If nothing designed the human mind, we have no more reason to assume it is designed to reason than to believe a milk spillage will show an accurate map of London. Thus, atheism is excluded. Uncertain worldviews tend to be contradictory, thus Agnosticism is excluded, because it destroys its own foundation. Every worldview, no matter how confident its followers may be, is philosophically flawed, simply because unless you think correctly about God, you have no reason to believe you can think correctly at all. Thus, faith in God is the most reasonable position.
