As you are probably aware, Help Me Believe is a blog focused on the subjects of apologetics and theology. In the past I have written to address the question, “What is theology?” but today I want to ask the question, “Why should we do theology?”
From the outside, it might be said that the world of theology is nothing more than bunch of nerds arguing about a bunch of stuff that doesn’t really matter. While some parts of that statement may be partially true, this is not necessarily the case. Does it matter how many angels can sit on the head of a pin? No, it does not. But does it matter that Jesus’s death made a way for sinners like you and I to be saved? Absolutely!
Very briefly, let me highlight three reasons we should do theology, the most important one being the last.
Because it increases our knowledge of the Scriptures
True systematic theology is built on the foundation of verse-by-verse and book-by-book study of the Scripture. You can’t properly jump into theology without first closely examining the text(s) your theology is based on. This means that “doing” theology (i.e., trying to figure out what the Bible teaches us about God, mankind, etc.), will require you to open your Bible and do more than read it. You will have to re-read it and study it and think about it and ask questions of it. And when you do all of these things, your knowledge of the Scriptures will surely increase.
Because it causes us to think rather than assume
Presuppositions are unavoidable. Everyone has a worldview, a lens through which they perceive everything that happens around them. This worldview also penetrates the way we think about God, ourselves, and the Bible.
In one instance, you might have grown up without attending church or learning about Jesus. This may cause you to be skeptical of the fact that Jesus even exists or that church is something you should be a part of. But when you open God’s Word and study it for yourself, you find theological principles that suggest Jesus is real, that He did die for your sins, and that you should become part of a local church.
In another instance, you might have grown up in a Christian home and were taught the Bible from a young age. But when you truly do theology, it may cause you to call into question some of the things you previously understood. Growing up as a Baptist, I thought for sure that I should believe in a pre-tribulation rapture. But when I began to study the issue for myself, I was not convinced. Rather than just assume what I had heard was true, I studied it for myself, thought about it for myself, and came to a different conclusion.
Because it leads to our worship of God
This is the real reason we should do theology. In fact, if your theology, your understanding of who God is, does not cause you to worship Him constantly, something is wrong! Ultimately, we study His Word and seek answers to difficult questions so that when we arrive at the proper understanding, we praise God for who He is and what He has done, is doing, and is yet to do.
I was recently reminded of this by two different works I have been reading. In Clinton Arnold’s commentary on Ephesians, he notes that the opening verses of the book teach us that “the study of theology should be combined with praise and adoration of our awesome God, who has done so much for us.” Also, in Chad Brand’s introduction to the book Perspectives on Israel and the Church: 4 Views (a highly debated theological topic), he writes, “it is my prayer that this exercise will lead you to greater depth of worship and to a more impassioned commitment to proclaim the gospel of our Lord and Savior, Jesus Christ.”
More than theology leading to worship, I believe we can even say that the very act of doing theology is itself worship. So, get to theologizing, and get to worshipping!
