Before I dive into the subject of why theological study is crucial for the Christian, I would really like to address something important. When you read the title of this post, you may have had certain doubts. You might have had one of these reactions: Theology? I don’t want to lose the simplicity of faith! Won’t I substitute thought for action? I mean, theology has caused divisions – theology uses big words, and it just complicates communication. Isn’t theology all based on speculation, and doesn’t theology major on minor truths? 

If you had a reaction similar to this, you’re not alone. You see, a large number of people in the church, unfortunately try to avoid theology and all that goes along with it like avoiding some plague. Most people have strong doubts about theology – but let me encourage you by saying that theology is not a bad thing. In fact, if theology is done with the right motive, it is a most glorious thing. With that said, let’s dive in deeper into why we should study theology and why it is definitely a good thing.

First of all, what is theology? Theology, in its literal translation is the study of God. The meaning of the word comes from two separate words: Theo (meaning God) and ology (meaning study). Essentially, theology is the study of God. Henry Clarence Thiessen gives us an even better way to understand the definition of theology, saying that “we may define theology as the science of God and His relations to the universe.”¹ Why is this? Why is theology the science of God and how He relates to the universe? Because in Christian theology, you have to include many different doctrines. Throughout years of study, we now include every Christian doctrine to this idea of theology. Doctrines such as:

• the doctrine of revelation (the study of how God reveals Himself to us, etc.)
• the doctrine of God (this includes His nature, His attributes, His decrees, His works, etc.)
• the doctrine of humanity (this includes our nature, and our relationship to both sin and a holy God)
• the doctrine of Christ (includes both the person and the work of Christ)
• the doctrine of the Holy Spirit (includes both the person and the work of the Holy Spirit)
• the doctrine of salvation (how it is that we are saved, what does that entail, etc.)
• the doctrine of the church (how is the church to be led, what is the purpose of the church, etc.)
• the doctrine of last things (consummation and what will happen when we die)

This was far from a complete list, but it definitely gives a good overview of what we consider to be theology today. It’s not just one idea, or a few scattered ideas – it is a science – the science of God. Theology is important because it deals with every day Christian life, as you can see clearly from the list above.

Why should we study theology? There are four main reasons why it should be important for Christians to study theology. So why should we sit down and enjoy studying theology?

1. Study Theology Because the Bible Teaches That Theology is Important

The first reason is because the Bible teaches us that theology is important. Look at Hosea 4:1-6:

“Listen to the word of the Lord, O sons of Israel, for the Lord has a case against the inhabitants of the land, because there is no faithfulness or kindness or knowledge of God in the land. There is swearing, deception, murder, stealing and adultery. They employ violence, so that bloodshed follows bloodshed. Therefore the land mourns, and everyone who lives in it languishes along with the beasts of the field and the birds of the sky, and also the fish of the sea disappear. Yet let no one find fault, and let none offer reproof; for you people are like those who contend with the priest. So you will stumble by day, and the prophet also will stumble with you by night; and I will destroy your mother. My people are destroyed for lack of knowledge because you have rejected knowledge, I also will reject you from being My priest, since you have forgotten the law of your God, I also will forget your children” (NASB).

In the beginning verse, God tells the people of Israel that there is a case against them – because on top of many other things, there was no knowledge of God in the land. And this is an essential part of theology. We as theological students try to learn more and more about our God. We need the right knowledge of God as Christians. This passage from Hosea calls us to pursue that knowledge, and it does so through one of its many warnings found in verse 6: “My people are destroyed for lack of knowledge, because you have rejected knowledge, I also will reject you from being My priest, since you have forgotten the law of your God, I also will forget your children.” If God is unchangeable (which is one of His many attributes), then He can do the same thing to us. We can be spiritually destroyed and reap the consequences without knowledge of God. We as Christians, as God’s people, need to have knowledge about God. Also, similar instruction is found in Malachi 2:7, “for the lips of a priest should preserve knowledge, and men should seek instruction from his mouth; for he is the messenger of the Lord of hosts.” In the local church, your pastor(s), deacons, elders, Sunday school teachers, or any other persons in leadership roles should help you in your personal study of the knowledge of God. This study is what we call theology. So first we see that the Bible teaches that study of theology is important.

2. Study Theology Because Jesus Demonstrated That Theology is Important

Secondly, we should study theology because Jesus demonstrated that theology is important. Let us look at Matthew 16:13-16:

“Now when Jesus came into the district of Caesarea Philippi, He was asking His disciples, ‘Who do people say that the Son of Man is?’ And they said, ‘Some say John the Baptist; and others, Elijah; but still others, Jeremiah, or one of the prophets.’ He said to them, ‘But who do you say that I am?’ Simon Peter answered, ‘You are the Christ, the Son of the living God.’” (NASB)

What is pictured in this passage is that they are walking in a line and Jesus goes to each disciple individually and asks these questions. When it says that Jesus was asking the disciples, it has the action of beginning to ask and kept asking. Finally, after he got through all of the disciples, he got to Peter. And Peter said that Jesus was the long awaited Messiah. The point: Jesus wanted to know what people were saying about Him. By doing this, He was demonstrating that theology is important to Him. If we cannot answer this fundamental question right, then we cannot dive further into theology, for if we have an answer any different than Peter’s, anything else we say is as flawed as the “wisdom” of this world.

3. Study Theology Because it is Important for Discipleship

Thirdly, to be a disciple we need to study theology. Remember, if we cannot answer who Jesus is correctly, we cannot begin to go anywhere else in Scripture. To be a true disciple of Christ, we have to know what Christ says, does, and thinks. The only way we can figure this out is by reading our Bibles and by studying theology. We need theology to help us in our walk with God. We need theology to be better ambassadors for Him. The Christian life may start out with a “blind” and simple faith, but God does not want us to stay there. God wants you and I to grow in our faith. God wants us to learn more about Him, and as we do we will be growing disciples.

4. Study Theology Because the Early Church Demonstrated That Theology is Important

Last, the early church demonstrated that theology is important. The early church had to rely on sound theology to safeguard against the all-too-frequent heresies that came about. Many of the major heresies really started after the apostle John died. Soon after his death was when Gnosticism was on its rise. This heresy affected people’s understanding of the doctrine of Christ, the doctrine of God, and the doctrine of humanity. If you ever decide to research Gnosticism, you will see that its impact was so sever that we are still trying to recover from this heresy. On a similar note, you even have to be careful when studying the heresies! Make sure you have a very solid foundation on the Bible before you work through those. There were many other heresies that came about that compelled the early Church to rely completely on sound theology. And that demonstrates the need for studying it.

Conclusion: Study Theology for the Glory of God

As I said in the introduction, if you study theology with the right motive, then it is a most glorious thing. Since we know why we should study theology, then we need to find out what the right motive is for studying theology. So what is this right motive? The answer to that is really the answer to why we do anything. We as Christians do everything to bring praise, honor, and glory to our sovereign King. That is always the end goal in everything that we do. Our motive for studying theology is no different. We study theology for God’s glory. If our motive is anything other than to learn more about our Creator, and to grow in our relationship with Him, then we are wrong and need to desperately repent. There are many who study theology so that they can answer all the questions, and be the smartest person in the room – quite plainly, that is wrong. They need to repent because it is clear that God is displeased with that. Truthfully, they would be better off not studying theology in the first place. So before starting to study theology, ask yourself why you are doing this. If the answer is not so that you can grow in order to glorify God, then wait until you can answer that way.
