Reality Check, or a Rant on my Hatred for Abstract Thought

I can't do abstract thought. There are philosophers and theologians whose ideas and arguments are based in thought so abstract and intangible that I cannot begin to conceive it. I'm sure that their ideas are valuable, I'm sure they're extremely intelligent and well-argued. However, their ideas are so far removed from reality, people, and life that I have no framework for conceiving of them. For example, Karl Barth's main argument, so far as I can tell, is that God is the ultimate unknown, that which we cannot know, and Christ came merely as an arrow that lets humanity know that God is unknowable.

I am a practical person. I love studying the way people and societies interact, I adore history, sociology and psychology. It's not that I insist on concrete ideas, I'm fine with mystery and ambiguity, but I need to be able to relate those things to some form of reality. If there is no basis in reality, what is the purpose of devoting time and energy to thinking about it, anyway? I am grounded in reality, in society, in time and history, in identity. No matter how hard I try, I can't imagine absolute void, I can't conceive of that which is wholly other, and I have no framework for thinking about that which is completely unknown. Furthermore, how is it helpful for people to spend time and energy attempting to contemplate things that are wholly unconnected with reality and life? How does thinking about God as "that which is unknown" help ministers to preach or provide pastoral care? How does that help Christians relate to the deity or grow in their faith?

I have trouble finding the value in ideas and studies that are disconnected from life. To me, what's most important is how we live and how we relate to others and God. I'm most interested in studying people, life, reality, and how those things shape our understandings of God. Maybe I'm too steeped in experience, maybe I'm too human-centered or don't have high enough Christology. But if I have no experience of something, if I cannot even relate it to something that occurs in the world, how can I have any understanding of it? Anything that has no connection with reality is a play of the imagination. And, don't get me wrong, I love using my imagination, but this is not how I choose to use it, and I have trouble playing logic games in the realm of imagination.

This problem with abstract thought occasionally makes me discouraged about my education and future career. I know that I need to be able to understand and explain some pretty abstract concepts. I am constantly told that they're important and valuable. But I'm more of a practical theologian. My gifts are in sociology more than philosophy. And I hope, with God's help, that'll be enough.
