Why Study Systematic Theology?

Our church has “equipping classes” instead of Sunday School classes on Sunday mornings before our worship service. One of the classes that we have this session is “Systematic Theology 1,” which is largely based on Wayne Grudem’s Systematic Theology book. It is a remarkable blessing for the church to offer this kind of teaching and two Sunday mornings ago there were 50 people in the small classroom listening to teaching on “The Attributes of God.” It is remarkable that a church offers this, but it is also remarkable that 20% of the church membership was sitting in a classroom wrestling with pretty heavy ideas about the character of God.

I think that one question that could come up about Systematic Theology would be “Why study Systematic Theology?” Is it just to fill your head and your ego with esoteric ideas? Is it to show how intellectual you are? Is there value in this study? I think the answer is an unqualified “yes.” The following are my thoughts on why study Systematic Theology.

First, it is required that we have a definition of what I mean when I say, “Systematic Theology” (ST). Real ST is necessarily rooted and grounded in the word of God. Speculations and extrapolations which deviate from the express teaching of the Bible are necessarily suspect. These are to be examined critically and, if they are found wanting, these speculations are to be rejected. On the other hand, the closer a given doctrine agrees with the explicit teaching of the Bible, the more vigorously that doctrine is to be held and defended. ST is the discipline that aids us in discerning and examining deeply these essential biblical teachings.

ST is a sanctifying activity, since it is the intense meditation on the word of God and what is taught therein.

ST deepens out faith in the Lord by allowing us to understand more about what the Lord has revealed to us about Himself and prevents us from merely speculating wildly (2 Cor. 10:5).

ST not only deepens our faith, but it simultaneously dispels our ignorance and pushes back the place where we say, “Well, I will just take that on faith.” Now, it is acknowledged that there is a place where everyone, no matter how biblically fluent, must confess that a given idea will be taken on faith. Deuteronomy 29:29 tells us that “the secret things belong to the LORD our God, but the things that are revealed belong to us and to our children forever, that we may do all the words of this Law.” ST helps us to see and understand “the things that are revealed” so we may obey our God and praise His name.

ST glorifies God, for just as the more we learn about the creation, the more we praise the Creator, so the more we learn about our awesome God and all that He has done for us in Christ, the more loudly and joyously we worship Him.

The speculations which come from the minds of fallen men and women pale into insignificance when compared to what God has already revealed about Himself and His work in His word. ST enables us to uncover and display in an orderly fashion all the treasures contained in God’s word and, when ST is done well, it helps us to remove the dross of man’s errant musings.

Imagine a 7-year old who has just learned her addition tables being told about algebra. Her knowledge has recently been extended to include addition, and now she is told of some strange new “math” that makes no sense to her ears. Addition has been revealed to her, but algebra is still a “secret thing.” For her, algebra is just something she must take on faith. It sounds fantastic and strange, and although she is not entirely convinced about this bizarre idea, our 7-year old is willing to take our word for it that algebra really is in a math book somewhere.

In the same way, a true believer will remain ignorant of biblical doctrines to the degree they are ignorant of God’s word. ST is one of the ways that a believer can emerge from their ignorance about what God has already revealed in His word. We do not “remain children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming (Eph. 4:14).” Rather, we are to grow up! It is not helpful or wise to take “on faith” what God has already clearly revealed in His word. So we make use of any and all means that God has provided to drive out our ignorance and to replace that with firmly grasped truth, and ST is one of those means.

Exodus 5:2 – But Pharaoh said, “Who Is the LORD?”

This post is part of a series from the book of Exodus. These posts share some of the riches which I discovered this year in my annual read through this Old Testament book about the LORD’s deliverance of His people from their slavery in Egypt.

In the fifth chapter of the book of Exodus, the LORD sends Moses and Aaron to Pharaoh to tell him that the LORD, the God of Israel, demands that His people be let go to worship Him in the wilderness. Pharaoh responds with these fateful words:

But Pharaoh said, “Who is the LORD, that I should obey His voice and let Israel go? I do not know the LORD, and besides, I will not let Israel go.” Exodus 5:2

The plagues of Egypt will come upon Pharaoh as a thundering answer to his reckless, arrogant question in Exodus 5:2. Defiantly, Pharaoh despises the LORD when he asks Moses, “Who is the LORD, that I should obey His voice and let Israel go? I do not know the LORD . . .” These sharp words create the plot for the plagues of Egypt and Pharaoh will live to regret these words. The LORD will make Himself known to Pharaoh through ten devastating plagues, and finally Pharaoh will die regretting these words, as the LORD destroys him and his whole army in the Red Sea. O, yes; Pharaoh will know the LORD.

For the LORD does not take defiance lightly. “Oh, you do not know Me, Pharaoh? Very well. Let me introduce Myself to you. I am the LORD. I rule heaven and earth, and if you will not bow down to Me, I will destroy you and your nation.” And the LORD hardens Pharaoh’s heart so that he will not repent of his defiance, in order that Pharaoh’s arrogance may be utterly extinguished by the punishing plagues from the LORD. The LORD makes sure that Pharaoh will never again be so foolish as to say, “Who is the LORD?” By the time this ordeal is finished, Pharaoh will certainly know who the LORD is.

Notice in these verses that, as the LORD brings His plagues on Egypt, many of them are brought so that Pharaoh and Egypt may know the LORD. Consider these verses:

  • 7:5 – “The Egyptians will know that I am the LORD, when I stretch out My hand against Egypt.”
  • 7:17 – “By this you will know that I am the LORD: Behold, I (Moses) will strike the water, and it shall turn to blood.”
  • 8:10 – (With the plague of frogs) This will be done, “so that you may know that there is no one like the LORD our God.”
  • 8:22 – There will be no swarms of flies in Goshen, “that you may know that I am the LORD in the midst of the earth.”
  • 9:14 – “I will send all My plagues on you, so that you may know that there is none like Me in all the earth.”
  • 9:29 – “The thunder will cease, and there will be no more hail, so that you may know that the earth is the LORD’s.”
  • 10:2 – “I have dealt harshly with eh Egyptians, that you may know that I am the LORD.”
  • 14:4 – “I will get glory over Pharaoh and all his hosts, and the Egyptians will know that I am the LORD.”
  • 14:18 – “And the Egyptians shall know that I am the LORD, when I have gotten glory over Pharaoh.”

The LORD does not forget or overlook the boastful, arrogant jeers of the any earthly monarch. Pharaoh was the most powerful man on earth at that time, but the LORD demands that He be worshiped, or He will destroy in judgment. “Our God is a consuming fire (Hebrews 12:29).”
