When we do evangelism, teach, or preach, we never recite the entire Bible in a single sitting. Instead, we rely on two necessary tools: Selective Representation and Interpretive Summary.

These tools are not only useful; they are essential. However, a specific danger arises when we fail to distinguish between the tools we use and the raw material of Scripture itself.

Defining the Terms

To understand how we communicate the Gospel, we must define the methods we are using:

1. Selective Representation This is the act of choosing specific verses to represent the whole counsel of God or the main claim of a passage. An example is when we choose to share John 3:16 rather than a genealogy from Chronicles to explain the Gospel, we are using selective representation. We are making a choice that a part implies the whole.
2. Interpretive Summary This occurs anytime you offer an explanation of a verse or the biblical message without quoting the text verbatim. If you read John 3:16 and then say, "In other words, this means..." you are engaging in interpretive summary. You are putting divine truth into your own words.

It is important to affirm that both of these practices are completely fine. In fact, they are unavoidable. It is what preaching is; it is how we teach; it is how we evangelize. We cannot communicate effectively without them.

We find biblical precedent for these methods. Jesus utilized them when He read a portion of Isaiah in the synagogue and provided the immediate commentary that it was fulfilled in their hearing (Luke 4:16–21). Philip utilized it with the Ethiopian eunuch, beginning with a specific passage the man was reading to preach the good news about Jesus (Acts 8:30–35). Similarly, Paul engaged in this practice in Thessalonica, where he reasoned from the Scriptures, explaining and proving that the Christ had to suffer and rise from the dead (Acts 17:2–3).

The Danger: Confusing the Summary with the Source

While these methods are necessary, they involve human agency. Our summaries and our selections are creative choices we have made. The danger arises when we forget that our interpretive summary is not the message itself, but rather a digest of the message.

The source is Scripture. What we say about the Scripture is an interpretive summary.

We risk elevating our interpretation to the level of inspiration. We must maintain the humility to admit which parts of our presentation are our own phrasing and which parts are the actual Scripture.

Common Examples of Interpretive Summaries

In modern evangelism, we use many phrases that serve as interpretive summaries. These are shorthand statements based on a selective representation of verses that the teacher believes represent the whole truth.

Examples include:

• "You must believe in Jesus for eternal life."
• "You have to trust in Jesus’s death, burial, and resurrection."
• "You need to accept Jesus into your heart."
• "You must turn from your sins to be saved."
• "Make Jesus the Lord of your life."

Each of these is a theological summary. While they may be derived from Scripture, they are often distinct from the verbatim text.

The Consequence: Misunderstanding Rejection

The most practical application of this concept lies in how we view rejection.

Because our presentation relies on our own creative choices (summary and selection), a listener might reject our specific wording without actually rejecting the Scripture.

If a skeptic pushes back against an interpretive summary, they may simply be disagreeing with your method of summary or your specific selection of verses. They are disagreeing with the thing you chose, not necessarily the saving message of the Bible.

The Misapplication of "Defending the Doctrine"

When the Apostles speak of "defending the doctrine," they are not referring to your selection and interpretive summary. They are instructing us to defend the actual deposit of truth that is the Scripture. The Bible is the doctrine. 

Any extrapolations we build on top of the Bible may or may not be correct, but they remain extrapolations. It is dangerous to take a Bible verse that commands us to defend the doctrine and apply it to our own creative choices. We must not claim divine authority for our summaries. To do so is to demand that others defend our words with the same vigor they would defend God's Word.

Conclusion

As evangelists and teachers, we must be intellectually honest and clear. We must distinguish between the perfect Word of God and our imperfect, though well-intentioned, summaries of it. By doing so, we ensure that when people engage with the Gospel, they are grappling with the text itself, rather than just our creative representation of it.
