CS Lewis or Søren Kierkegaard ?
Kierkegaard, to some extent yes, he has a lot of insight on various things and does hammer home a lot of great seldom contemplated ideas in Christian doctrine.
CS Lewis though, not really, he was always more of a fiction writer than a theologian or philosopher. "Lewis' Trilemma" is one case-in-point towards terrible arguments that should be viewed shamefully, especially by Christians.
I think it's a quite unreasonable to expect from finite beings reasonings that could explain entirely all the things revealed by an infinite being knowing how limited our understanding of things is today.
We don't even fully understand a universe we see with our eyes.
This is no secret. The point here is that adhering to an unquestionable, exclusivist dogma and/or doctrine at the level of antogonizing others requires equally strong intellectual, logical, rational etc understanding. Without this, all the person has is strong opinions. Strong opinions without any reason to have them are worthless.
When it comes to the complexity of existence though, I don't think we are willing to admit often that in the face of that complexity is supreme simplicity. What you ask or allude to here is an epistemic question about the nature of knowledge, which comes back to the root of the nature of being.
As I've seen in your other posts, you're clearly a Christian, so you are likely philosophically an idealist (even if you didn't recognize it as such), not a materialist. That's a good start for such a question.
Alongside the nature of knowledge itself, the question of "can truth be known?" is another question worth asking.
If truth can be known, then what is that truth? and where/how can it be found? and if truth can't be known, then how can we hold onto worldviews (including politics and morality) and religions with any sense of authority?
It's a very long progress of defining and re-learning one's approach to existence, being, morality, ideology and ultimately God too.
Many secular philosophers after Nietzsche (as he had an impact on Western thought that came unexpected to Western philosophy, culture and religion) really battled it out from his own conclusions, two of the most notable were Wittgenstein and Heidegger, then we had the school of absurdists (like Camus) as well.
It's important to have actual serious contemplation of these issues in determining one's faith, religion and the nature of both.
History is full of intellectuals, from every field and religion, it's a shame that certain majoritys of religious groups choose to be willfully ignorant to even the most simplest things about existing and the wealth of knowledge their religions have in their histories.
Now many that have lurked this thread may interpret me as bashing Christianity but I don't and I say and ask these things with complete sincerity, these are things that are very very important to me and to Faith itself. I ask and challenge things because I care.
