What is the best approach to doing biblical theology? Two different perspectives have become popular among Evangelicals.
In this series on how biblical creationists can improve their promotion and defense of Genesis 1–11 as being historically accurate, we have now looked at two topics from these chapters—the days of creation and the meaning of the 120 years mentioned in Genesis 6:3. I plan to cover at least two more passages in upcoming posts, but before I get to those, I want to spend some more time describing and defining biblical theology. In the first post, I contrasted it with systematic theology to show how it differs from that common approach.
In this article, I want to show how several different writers have defined biblical theology, because there are some different schools of thought concerning what it means to truly do biblical theology. For lack of better terms, I’m going to label these as the Mostly Inductive Approach and the Less Inductive Approach. Please note, you won’t find others using these labels; I made them up (as far as I know) for the purposes of this post. I’m not satisfied with these labels, but they will suffice for now. There are other ways people define biblical theology, but I believe it is safe to say that these are the two most common views among Evangelicals. Generally speaking, proponents of both sides affirm the inerrancy, authority, and divine inspiration of the Bible, and both sides affirm that salvation is by grace alone through faith alone in Christ alone. They simply have different opinions over what biblical theology is or how is should be carried out.
The Mostly Inductive Approach
In the Moody Handbook of Theology, Paul Enns stated the following:
…biblical theology is…that methodology that takes its material in an historically oriented manner from the Old and New Testaments and arrives at a theology. It is exegetical in nature, drawing its material from the Bible as opposed to a philosophical understanding of theology; it stresses the historical circumstances in which doctrines were propounded; it examines the theology within a given period of history (as in Noahic or Abrahamic eras) or of an individual writer (as Pauline or Johannine writings).1
So, in doing biblical theology, we focus on exegesis. This is a careful inductive study of determining, to the best of our abilities, what the text actually says and means. We study Scripture in chronological order according to when it was written to discover themes and see how doctrines developed in light of the historical circumstances in which the biblical writers lived. It doesn’t start with preset categories and then search the Bible for the data to fill those categories as systematic theology does. Also, it limits the data to what can be found in Scripture, whereas systematic theology often incorporates extra-biblical data. Finally, as the name I gave it implies, it is an inductive approach to doing biblical theology because it doesn’t set out with the answers already in mind.
In the first article of this series, I cited Eugene Merrill’s description of biblical theology. He also defined the task of the biblical theologian this way: “The biblical theologian must work his way through the biblical text, inductively and progressively discovering its theological truth. In the process he may or may not discern patterns and paradigms, but he must make the effort to extract principles that provide the hard data for synthesis.”2
This is probably the clearest explanation of biblical theology I have found. Merrill nailed it. He highlighted the inductive nature of biblical theology—we don’t start with the answers, we discover them through careful study. He also pointed out that the researcher may or may not discern patterns and paradigms. I believe this is an important point to keep in mind, because as we’ll see in the next section, so many theologians attempt to do biblical theology assuming certain patterns and paradigms from the outset.
Progressive Revelation
Merrill also pointed out that we must keep in mind that the Bible was progressively revealed. In case you are not familiar with the concept of progressive revelation, it simply refers to the fact that the information God revealed about himself and his plan was given to man bit by bit over time rather than one big info dump. So, Adam and Eve may have known a small part of God’s plan. God revealed more of his plan to Abraham, and more to Moses, and more to David, etc. This means that we should not expect earlier biblical figures to have had as much knowledge of God’s plan in human history than later biblical figures.
Paul revealed this truth in the way that he used the term “mystery” to describe teachings that were hidden from the Old Testament saints but had now been revealed in his time. For example, in 1 Corinthians 2:7–10, a passage that is frequently misused by Christians to talk about the unimaginable glories of heaven, Paul comes right out and said that there were things hidden from earlier believers that had recently been made known.
But we speak the wisdom of God in a mystery, the hidden wisdom which God ordained before the ages for our glory, which none of the rulers of this age knew; for had they known, they would not have crucified the Lord of glory.
But as it is written: “Eye has not seen, nor ear heard, nor have entered into the heart of man the things which God has prepared for those who love Him.”
But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. (1 Corinthians 2:7–10)
Paul also used mystery to describe events related to the future bodily resurrection of believers (1 Corinthians 15:51–53) and while discussing the church, an entity consisting of believing Jews and Gentiles (Ephesians 1:9; 3:1–7). Each of these concepts were either absent from Old Testament teaching, or they were there in embryonic form but certainly not given any emphasis until God revealed them in New Testament times. By the end of this article, I will explain why this brief detour into the doctrine of progressive revelation was relevant to our study.
The Less Inductive Approach
Let’s look at some definitions that I have classified as being less inductive and I think muddy the task of biblical theology. In the book 40 Questions about Biblical Theology, the authors focus on defining biblical theology in the first chapter. They provide both a short and long definition.
Shorter definition: Biblical theology studies how the whole Bible progresses, integrates, and climaxes in Christ.
Longer definition: Biblical theology is a way of analyzing and synthesizing the Bible that makes organic, salvation-historical connections with the whole canon on its own terms, especially regarding how the Old and New Testaments progress, integrate, and climax in Christ.3
While many Christians would agree with these definitions, I see a problem with the first definition and a few problems with the second. In the short definition, the authors show that they have already decided what the major theme of the Bible is before they even start doing biblical theology. They have a definite goal in mind rather than allowing the Bible to reveal the themes and doctrines. Of course, I would agree that Jesus Christ’s ministry, sacrificial death, and resurrection are the most important events that have ever occurred on earth and are huge themes in Scripture, but biblical theology shouldn’t start with the conclusion. If one begins with this definition, then his attempt to perform biblical theology will not truly be an inductive study.
The longer definition has the same problem as the first, but it adds a couple more. The authors stated that it “makes organic, salvation-historical connections…” I believe the authors are inserting a bias that a major theme or the way to read Scripture is through “salvation-historical connections.” This statement is contrary to Merrill’s point that the researcher may or may not find patterns or paradigms. These authors start with a paradigm in mind, thus there may well be a tendency for the researcher to engage in eisegesis as he tries to interpret a passage in a manner that fits his preconceived paradigm.
Also, this statement about salvation-historical connections sounds like they are advocating what is known as the redemptive-historical hermeneutic, which essentially teaches that the way we should read Scripture is to find what it can tell us about Jesus and God’s plan for redeeming mankind. While there are many who have adopted this approach, particularly within Reformed traditions, this is a framework imposed on the text—it is not derived from it. My suspicions grew stronger a few pages later in the book where the authors stated, “When we read any part of the Bible—including the OT—we must read with Christian eyes” (emphasis in original). Of course, it is impossible for Christians to completely set aside our beliefs about Jesus and our knowledge of the New Testament, but when doing biblical theology, we must do our best to discover what the biblical writer and original audience thought about the text rather than imposing our views onto the text.
This same type of approach can be seen in Brian Rosner’s definition in The New Dictionary of Biblical Theology, where he stated the following:
To sum up, biblical theology may be defined as theological interpretation of Scripture in and for the church. It proceeds with historical and literary sensitivity and seeks to analyse and synthesize the Bible’s teaching about God and his relations to the world on its own terms, maintaining sight of the Bible’s overarching narrative and Christocentric focus.4
The popular biblical theology textbook by Gentry and Wellum, God’s Kingdom through God’s Covenants, wholeheartedly endorses Rosner’s definition, quoting it verbatim.5 Notice that these authors assume from the outset that the Bible has a Christocentric focus. Again, I am not denying that the Lord Jesus is the central figure of Scripture, although one could also make the case that God the Father is central or that the Bible is theocentric (God-centered) rather than Christocentric. But it is what these authors mean by Christocentric that can easily lead us into dogmatic theology instead of truly performing biblical theology.
Furthermore, when they describe the task of biblical theology as a “theological interpretation of Scripture,” it raises a red flag in my mind. Do they mean that it’s a theological interpretation, as opposed to a naturalistic one employed by most liberal scholars? If so, then I would not take issue with their use of this phrase. Clearly, the Bible is a book full of theology (teaching about God and his interaction with his creation), so to remove these elements from one’s study of the text would necessarily cause one to miss its meaning. However, if by “theological interpretation of Scripture” the authors are referring to the tendency among covenantalists to read later theology (particularly about Jesus and redemption) into Old Testament passages, then I would strongly object since this approach does not allow for the text to stand on its own.

The New Dictionary of Biblical Theology provides a good example of the Less Inductive Approach to biblical theology.
D. A. Carson also provided a definition for biblical theology in The New Dictionary of Biblical Theology, and I think he handled it a little better than Rosner, at least initially. He stated, “biblical theology focuses on the inductive study of the biblical texts in their final form, seeking progression towards greater and greater faithfulness”6. I think his description of biblical theology as an “inductive study of the biblical text in their final form” is a great way to describe the task of biblical theology. However, in the next sentence, Carson added, “the discipline as a whole must strive toward the elucidation of the biblical documents along the axis of redemptive history…” And then in the next sentence, he wrote, “On the one hand, biblical theology will try to preserve the glorious diversity of the biblical documents; on the other, it will try to uncover all that holds them together, sacrificing neither historical particularity nor the unifying sweep of redemptive history.”7 Did you notice the italicized words in these two sentences. It is quite common to see authors use the term “redemptive history” when describing their approach to interpreting Scripture. What they often mean by this, is that they attempt to interpret Scripture through the lens of what it tells us about Jesus and/or his atoning work on the cross, rather than simply trying to determine what the text says. Thus, there has been a tendency among these theologians to use later revelation to reinterpret earlier passages to make them say something about Jesus and/or man’s salvation when the passage may not actually be about these matters.
Which View Is Better?
Since there are conflicting ideas of how to define biblical theology, it may not be fair to say that one of the two positions provides a more accurate definition than the other. That being said, I believe the Mostly Inductive Approach offers greater value to those seeking to properly understand the biblical text. By striving to understand a given passage in the same way as the original audience might have understood it, we are likely closer to discovering the author’s intended meaning.
In many ways, the differences outlined above are consistent with some of the distinctions between Dispensationalism and Covenantalism. Dispensationalism is primarily a way of exegeting and interpreting the text in a manner that emphasizes the passage’s original meaning. Covenantalism can be likened to a theological framework based on certain Reformation era presuppositions that are imposed onto the text.
Multiple objections can be raised against the second approach. By opting for some form of Christo-centric or redemptive-historical hermeneutic, supporters of this view have created, perhaps unwittingly, some concerning problems:
- First, implicit in their determination to read older revelation through the clearer lens of newer revelation, proponents of this view are essentially saying that the older texts cannot stand on their own. Instead, they need to import ideas from later revelation. While more recent revelation can illuminate previous passages, they should never cause us to reinterpret older revelation or import a foreign meaning into the passage.
- Second, it flows from the first point that the original audience could not have obtained a proper interpretation of the revelation God had given them. After all, if one needs later revelation to (re)interpret previous revelation, then how could the original recipients of said message ever properly understand that? And yet Scripture repeatedly shows that God holds people accountable for their response to the revelation they have been given. If they could not understand that revelation because the clarifications of later revelation had not yet been revealed, then how could God justly hold them accountable for something they could not possibly know?
- These points would also seem to imply that the Holy Spirit didn’t quite get it right the first time that he inspired the text to be written. However, once he inspired the writing of the New Testament books, then he was able to make things right. Obviously, no Bible-believing Christian would believe that the Holy Spirit made a mistake and I’m confident the authors I cited above would not believe this, but this conclusion can easily be drawn from the premises laid out by those seeking to read earlier revelation through the lens of later revelation.
- Finally, interpreting the text via a Christological lens or a redemptive-historical lens could be seen as either a repudiation of progressive revelation or a drastic reduction in the amount of information that God withheld from earlier biblical figures. On that view, we should probably assume that our Old Testament heroes knew far more about God’s redemptive plan than they ever let on.
For these reasons and more, I believe that the Mostly Inductive Approach to biblical theology described by Enns and Merrill will yield more valuable results in our study. By attempting to put ourselves in the minds of the original audience, we will often force ourselves to think through the text in ways that can enhance or correct our traditional understanding of a given text. On the other hand, the position described by Carson, Rosner, and others above adds little to the study of theology and imposes a later theological framework onto earlier biblical passages. In some ways, it encourages us to simply adopt what others have already said about the text.
Insights from Writing Historical Fiction
It may seem odd to conclude this blog post with insights I learned while writing some of my novels, but I think this will help shed light on these two approaches in a way that can cut through the theological jargon above. While writing The Remnant Trilogy, three historical fiction novels about the life of Noah up until the time of the flood, I had to repeatedly try to put myself in Noah’s mind (more accurately, my fictional conception of Noah’s mind). This meant that I could not use later revelation to flesh out his knowledge. While I could have Noah speak of God’s judgment on humanity once God revealed that to him, I could not have him describe Christ’s sacrificial death and resurrection because those things had not happened yet and they had not been revealed to man yet.

Writing The Remnant Trilogy gave me plenty of practical experience in doing biblical theology. I was not able to import later revelation into Noah’s knowledge base or his culture. I limited his knowledge of God’s revelation to certain details described in Genesis 1–6.
I was limited to the first six chapters of Genesis, and even then, I couldn’t just assume that Noah knew all of the details from those chapters. Did he have written or oral records with those details? We can’t know that. I proceeded as though his family had passed down some of the information from the Bible’s earliest chapters, but Noah was not aware of all of it, and he still need to decide whether he would believe information that might have sounded legendary or mythical in his day. Was there truly a talking serpent? Was his great grandfather Enoch taken up into heaven without dying? (Of course, I believe these are true – I’m simply making the point that someone in Noah’s time might find them hard to believe.)
I have heard many creationists state that Noah could have learned all these details because his grandfather (Methuselah) knew Adam. If the Masoretic Text contains the correct chronology in Genesis 5, then their lifespans overlapped for more than 200 years, so it is within the realm of possibility that they knew each other. However, there is no reason to assume that Methuselah knew Adam and received information about these early chapters directly from the first man. But Adam was his great…great grandfather, so he must’ve known him, right? Adam was everyone’s father, grandfather, great grandfather, etc. He might have had hundreds of thousands or millions of descendants by the time Methuselah was born. Why should we assume that he kept in touch with this one particular distant descendant?
Conclusion
By limiting Noah’s knowledge of God’s plan to what is revealed in Genesis 1–6, I believe my depiction of him made him a much more relatable and realistic character. Of course, it is possible that he knew more about these matters than what Scripture tells us, but we simply have no way to know this.
And so it is with biblical theology. I believe we should adopt an approach that strives to understand the text the way the original audience might have understood it. Yes, we have the great benefit of later revelation that reveals many more details of God’s plan, but we should not impose our knowledge into the minds of our distant forebears who were not privy to this information.
In his infinite wisdom, God chose to reveal his plan to us through progressive revelation. And we can study that revelation in a variety of ways. We can engage in systematic theology, historical theology, practical theology, and a number of other theologies. But if we are to do biblical theology, then I suggest that we allow it to be a distinct discipline that is both exegetical and inductive while honoring progressive revelation. I believe such an approach will be highly beneficial to biblical creationists as we insist on allowing authorial intent and the context of the original audience to carry greater weight than details revealed or discovered centuries or millennia later.
May the Holy Spirit guide each of us as we prayerfully and carefully seek to rightly divide the word of truth.
