This is what faith really should involve. I agree that it’s hard to understand the universe and God as a whole, but I wouldn’t say we’re incapable of understanding it; it’s just that most, if not all, of us, need to dedicate our intellectual resources to more worldly matters for too much of the time. Faith gives us confidence that there are answers, but that shouldn’t stop us looking for them. It shouldn’t mean “blind belief in the face of the evidence” - it ought to express our trust in God to “do the right thing”, our belief that His world is good and logical and ultimately perfect, even if we can’t, with our limited understanding, grasp the entire truth of everything in an instant. But that’s not to say we should abandon intellectual enquiry, which (unfortunately) lots of people seem to. As Anselm put it; Neque enim quaero intelligere ut credam, sed credo ut intelligam. I don’t understand so that I can believe, I believe so that I can understand.
I agree that there’s no point in following Christianity, or any other religion, just because it “makes sense” from a purely intellectual point of view. You need to know God in your heart, to seek something beyond this world, to desire faith, or enlightenment, or love, or however you prefer to express it. There are many ways of starting on this path; contemplation of the beauty of the world, the power poetry and art, our own imperfections and desire for something better - but that first step needs to be taken in your heart, not just in your head. And, while it would be irresponsible of me to actively endorse Liberal’s use of certain - shall we say - physical means of assistance - towards this, I am given to understand (cough) that it’s by no means ineffective. 
Another point I should make. God doesn’t punish us for “not understanding”, or even for not having faith. God punishes us for being sinful. I don’t see how an honest intellectual enquiry into the nature of things which leads you to reject some aspects of the Christian faith as presented by some Christian churches can be sinful; however, there are plenty of other ways, which everyone will recognize as “wicked” or “evil” or “immoral”, in which we can, and do, sin, and that sin is what cuts us off from God. Can any of us honestly say that they’ve never done or said anything evil, even by our own personal standards rather than the arbitary standards of some church or law? I know I can’t.
(I know that cosmosdan will take exception to the word “punish”. Perhaps “repay appropriately” would be more neutral; I certainly know that an appropriate repayment for my actions would count as punishment, at least.
