My advice is when you first start realizing this about yourself, is just to ride the wave. Go join a Bible study and get the in-depth theology texts you want to read. The Bible study is your best chance to connect with other deep thinkers. Frankly, if that’s what you really want, just go to all the Bible studies, whether female or co-ed. You’ll run into some shallow chatty women there too sometimes, but once the study gets going, you’ll find yourself getting a lot of deep thinking and connection over God’s word. Sometimes non-denominational churches call Bible studies “life groups” these days, it’s the same deal.
The goal for a deep thinking Christian, ultimately, is to solve complex spiritual problems in the power of the Holy Spirit. Most people don’t think of Bible studies as “service” but it really kind of is because God uses His Word to illuminate the problems of the people in the Bible study group, kind of like a think tank for Biblical thought. So yes, there are deep thinkers is almost every church, and usually a Bible study is a good way to join them. And yes, there are men and women of the faith who are deep thinkers their whole lives, spending half their lives reading theology books and looking things up in their Strong’s Exhaustive Concordance. My mom and uncle were precisely the type. You’re in good company.
For me, while I still enjoy deep thinking sessions and in-depth research, I find that I need to take breaks and vary up my day with more stimulating activities like sewing and muscle training, otherwise I start to feel like I’m in a sensory deprivation tank, and that’s not a good feeling. But that is only me, and someone else might have an easier time of it. I hope you find your way into a supportive Bible study soon.
