introduction
One of the greatest needs our culture has at this moment is understanding what the Bible says and the proper way to interpret and apply what has been read. Interpreting passages wrongly gives us a skewed perspective of who God really is and what He has promised us through the gospel. On the other hand, a close and careful reading allows us to see Him as Scripture proclaims.
One of the best tools to accomplish this is text flow diagramming. You may have heard this method referred to as block diagramming, semantic diagramming, text hierarchy, phrasing, or numerous other labels. The main gist of a text flow is to visually layout a passage of Scripture so that you can clearly see the main points of a passage. It is done through a several step process that includes careful reading of the text several times and then proceeding to allow the main clauses to stand at the left-hand margin while indenting the subordinating clauses and phrases under the main clause(s). The result is a visual stair step (or block) like aid that represents the flow of thought of the author. Below is an example from Galatians 1:1-5

A brief glance at the diagram reveals the main thoughts of Paul and his companions writing and their desire that God would give them grace and peace through the person of Jesus. It doesn’t sound too spiritual but those are the main points in Paul’s introduction to the Galatians.
Some Words of Caution

It’s tempting to see a Scripture that really stands out and try to force it to be the main point. Text flow diagramming, although flexible and not as rigid as line diagramming, is bound by grammatical rules. How we “feel” about a particular verse does not automatically mean it should stand as the author’s main theme or the central focus of an entire pericope. Therefore, it is important to let the author’s meaning and the grammar (which will be discussed in a follow-up post) dictate what the main point is.
One last caution would be understanding that text flow diagramming is a starting point and should never be the only part of your Bible study. You need to put the work in and dig as deep as you can with other resources. You can see some of my favorite tools on this page.
how is text flow helpful?
Besides laying out the main points visually, text flows are useful as a study aid in several ways:
- Text flows give a bird’s eye view of an entire passage. Scanning the page will help you see the big picture of a pericope and the main topics the author is trying to drive home.
- Text flows provide a natural outline. Since the main points are available at a glance you can easily outline a passage. The subordinating clauses often serve as sub-points, helping to flesh out the main clauses.
- Text flow syntactical labels (discussed at a later time) help identify the connection of individual clauses and phrases to the main clause.
- Text flows when done properly, align closely with the grammar of the original languages. (this is mainly the Greek text. Hebrew is different.)
- Text flows are easier to learn than traditional diagramming.
- Text flows still force you to slow down and observe the whole text.
the tutorial outline
Our journey to understanding the Bible will be taken in steps. It is important to try and learn these concepts well. After every step, practice what you have learned by reading a familiar Bible passage and picking out the key elements you learned that day. Let’s get started by looking at the outline
Step 1 – Basic Grammar
We will identify the basic grammar essential to understanding the Bible. Scripture was written according to the grammar and syntax of the time and it is important for us to understand it, as well. This lesson will cover the following:
• How to find subjects, verbs, direct objects, and indirect objects
• Different types of verbs
• Apposition words
Step 2 – Clauses and Phrases
This lesson will focus mainly on how to identify clauses and phrases. And yes, they are different.
• What are clauses?
• What are phrases?
• Different types of phrases
Step 3 – Identifying Propositions
This is where we begin to dig into the text. Everything we’ve learned up to this point will come into play, so make sure you learn the previous lessons well.
• Finding propositions
• Splitting propositions
• when some propositions stay together
• Prepositional Phrases and their contribution to the text
Step 4 – Indenting Subordinating Clauses
This step will go into detail on how and where subordinating clauses should be indented.
• Two methods of indentation
• Extracting phrases
• “Testing” subordination for correct placement
• Using arrows to show subordination
Step 5 – Semantic Labels
We will identify and place semantic labels beside each subordinate clause.
• Categories of semantics
• Color coding schematic of labels
Step 6 – Final Touches
In the last step we will see what is done once we finish the text flow.
• Proof reading your diagram
• Internalizing your study (how is God’s word changing you?)
• Creating an outline
• Further study
I pray that text flow diagramming will be another useful tool in your Bible study belt. It will take practice and perseverance just like any other skill. But once you get the hang of it, I think you will find that it will be one of the most important steps in the observation phase of your study.
