Concept

Lesson 5.4, Practical Tactics

Intro

Knowing apologetics is one thing. Using it in a real conversation, in the kitchen, on the bus, after class, in the comment section, is another.

This lesson gives you four working tools. Three are borrowed from teachers who have spent decades doing this kind of work: Greg Koukl, Tim Keller, and C. S. Lewis. The fourth is the most important one of all, the bare ninety-second gospel you can deliver in your own words without a script.

Koukl's Columbo method is asking small, calm questions that put the burden of explanation on the other person. ("What do you mean by that?" "How did you come to that conclusion?" "Have you ever considered...") It is not a trap; it is a way to listen carefully and let the conversation breathe.

Keller's show, do not tell posture says you do not have to dunk on people. You can grant the strong form of their objection, repeat it back better than they said it, and then quietly offer what Christianity actually teaches. People who feel heard listen.

Lewis's trilemma (liar, lunatic, or Lord) still works when the topic is Jesus' identity, but only when the moment is right.

Then there is the hard case: the person who knows the case is true and still will not say yes. That person is not a tactical problem. They are a heart-and-Spirit problem. The right response is patience, prayer, and presence, not more arguments.

The lesson lays out each tool, when to use it, when not to, and how to keep the gospel in the center the whole time.

In full

This lesson is hands-on. Three teachers, Greg Koukl, Tim Keller, C. S. Lewis, have each given the evangelistic apologist a tool that earns its place in the bag. Plus the core drill: the ninety-second gospel. Plus the hard case: the convicted-but-resistant person, the one who knows the case is true and is still not willing to come.

The goal is to put working tactics in the apologist's hand: use Columbo questions, hold the show-don't-tell posture, walk through the trilemma if it fits, deliver the ninety-second gospel, and spot the shape of resistance that is no longer about the mind.

Required reading

Closing Conversations, the cluster's working treatment of closing well. Re-read the section on common patterns. The tactics in this lesson plug into that frame.
Conversation Scenarios, worked examples of evangelistic conversations with the moves marked. Read three or four. Pattern-spotting is the goal.
Quick Objection Responses, short responses to common objections, so an apologetic side-trip does not derail the evangelism arc. By Module 5 you know the deep responses. You also need the short ones.
Meaning-Centered Evangelism, the corrective to manipulative or program-driven methods. Tactics serve content. Content does the work.
Liar Lunatic or Lord, C. S. Lewis's trilemma framing. Read the argument page so you know when it lands and when it does not.

Key takeaways

Tactics serve content. They do not replace it. A clever Columbo question without the gospel behind it is just a move. The content is what saves. The tactics set up the doorway.
The right tactic depends on the seeker. A philosophy student wants different scaffolding than a tradesman. A hostile person wants different posture than a tender one. Read the person, then pick the tool.
The ninety-second gospel is non-negotiable. Every other tactic is optional. The bare apostolic gospel, ready to deliver in your own words without notes, is the core drill. Memorize it. Rehearse it. Say it out loud until it is speech rather than recitation.
The convicted-but-resistant person is not a tactical problem. This is the person who knows the case is sound and still will not say yes. The right response is not more argument. It is patience, prayer, and presence. Sometimes the right response is to step back and let the Spirit work.
The apologetic conversation is allowed to slow down. Tactics are not levers for speed. The Spirit's timing is not the apologist's timing. A conversation that ends in I need to think is not a failed conversation. It is, often, a conversation paused at the right moment.

Greg Koukl, Tactics and the Columbo questions

Greg Koukl's Tactics is the standard modern handbook for one-on-one apologetic conversation. Its core insight is that the apologist's first job is not to answer. It is to understand. Most apologetic conversations go badly because the apologist starts arguing against a position he has not yet understood. Koukl's fix is the question.

The "Columbo" method, named for the detective who solved cases by asking small, polite, disarming questions, has three steps.

What do you mean by that?, the clarifying question. Forces the seeker to define his terms. A seeker who says "I don't believe in organized religion" might mean a dozen different things. The apologist who responds before clarifying is arguing against a target he cannot see. Ask first.
How did you come to that conclusion?, the reasons question. Puts the burden of proof where it belongs. The seeker who has made a confident claim is now invited to give the reasons for it. Often the reasons are thin. Sometimes the seeker sees this on his own without the apologist having to argue at all.
Have you considered...?, the gentle counter-question. Once you understand the position and the reasons, offer a different view to consider. Not as a takedown. As a question. Have you considered that the existence of evil might be evidence against naturalism rather than against theism? The question is easier to engage than a head-on claim.

Why this matters for the transition. Columbo questions take pressure off the apologist (he is not the one making all the claims), soften hostility (questions feel less aggressive than counter-arguments), and slow the conversation down enough that the recognition signals from Lesson 5.2 have time to appear. A conversation done in Columbo mode is far more likely to produce the conditions for the transition than a conversation done in lecture mode.

Worked example. A seeker says: "Religion is responsible for most of the wars in history."

What do you mean by religion, all religions, or Christianity specifically? And what do you mean by "most"?
How did you come to that conclusion? Where did you read the figure?
Have you seen Vox's encyclopedia of war count, only about seven percent of historical wars are linked to religion at all, and a much smaller fraction to Christianity? If the number is much smaller than you thought, does that change anything?

The exchange is humble, slow, and disarming. It is also far more effective than the apologist launching straight into a defense.

Tim Keller, show, don't tell

Tim Keller's contribution to evangelistic apologetics is posture, not technique. The Keller correction is that the Western seeker, especially the modern city skeptic, is rarely won by argument alone. He is won by being shown that Christians are different, then by being given reasons that make the difference make sense.

Three parts of the Keller posture.

Take the seeker's objections seriously, on their own terms, before answering. Keller is famous for restating the strongest form of the objection, often stronger than the seeker would state it himself, before responding. The effect is disarming. The seeker sees that the apologist is not afraid of his question.
Show the cost of the seeker's own position. Every worldview has commitments most of its holders have not examined. Keller's pattern is to ask: what does your worldview cost you, that you have not yet noticed? If naturalism is true, what happens to meaning, to moral duty, to love as more than chemistry? The apologist does not argue against the seeker's position. He invites the seeker to see what the position is actually charging.
Commend Christianity culturally before defending it in the head. Show that Christianity is beautiful. That Christians live differently. That the gospel produces a kind of life the seeker is unlikely to find elsewhere. Then offer the reasons. The cultural commendation lowers the seeker's defenses. The mental case lands on softer ground.

Worked example. A modern skeptic objects that Christianity is limiting. The Keller move is not to defend Christianity's freedom in the abstract. The move is to ask: what kind of life does your own worldview produce, and is it the life you actually want? Combined with: the freest people I know are old saints who have surrendered everything. Have you met them?

C. S. Lewis, the trilemma

Lewis's most famous argument is the trilemma: Jesus claimed to be God. Therefore Jesus is either a liar (he knew his claim was false), a lunatic (he truly believed a false claim of being God, which would make him insane), or Lord (his claim is true). The argument is laid out at Liar Lunatic or Lord in its debate-prep form. The apologist should know its premises, its objections, and its proper use.

For evangelistic apologetics, the trilemma has one main use. When a seeker has expressed respect for Jesus as a teacher but not as the Lord, the Lewis pattern makes the seeker face the problem of good teacher as a stable category for someone who claimed to forgive sins, claimed to share the Father's authority, and accepted worship. The frame closes the door on the lukewarm-admirer position.

When to use it. When the seeker has said something like Jesus was a great moral teacher or I respect Jesus, I just don't think he was God. The trilemma reframes the seeker's own posture as shaky.

When not to use it. Against a seeker who has not granted Jesus's teaching authority at all, or against a seeker who is well-read in the legends-grow-fast objection. There the trilemma does not yet have purchase. The apologist needs to do groundwork first.

Worked example. You said Jesus was a great moral teacher. Most of what he taught was about himself: that he forgives sins, that he shares the Father's authority, that he is the way to God. If he was wrong about that, he was either lying or insane. A great moral teacher who lies about his own identity at every turn is not great. A great moral teacher who is insane about his own identity is not great either. What if he was right?

The ninety-second gospel

Every apologist needs an unscripted, in-his-own-words gospel that fits in roughly ninety seconds. The drill is non-negotiable.

A clean version, ninety seconds spoken naturally:

There is one God. He made the world, and He made you on purpose, to know Him and walk with Him. We have all chosen, every one of us, to live as if He were not the center. The Bible calls that sin. Sin separates us from God, and the wages of sin is death. But God did not leave it there. He sent His Son Jesus into the world. Jesus lived the perfect human life that you and I have failed to live. He went to the cross and absorbed the death our sin had earned. He rose again on the third day, alive, and is alive right now. He is calling you, personally, by name, to turn from your sin, trust Him, and come home. If you say yes, He will forgive every sin you have ever committed, give you His own Spirit to live inside you, and walk with you the rest of your life and into eternity. That is the offer. That is the gospel.

The drill. Write your own. Use your own vocabulary. Avoid Christianese where you can. The seeker should be able to understand every sentence. Deliver it out loud, into a phone recorder. Listen back. Adjust. Run it until it sounds like speech, not recitation. Do this five or six times until it is yours. Then practice it in low-stakes settings, to a fellow believer, to your reflection in the mirror, to your dog, until you could deliver it at a kitchen table without notes.

Handling the convicted-but-resistant person

This is the hardest case. The seeker has heard the apologetic case. He grants that it is strong. He is not refuting the case. He is not coming anyway.

The mistake is to treat this as a tactical problem. It is not. It is a human problem. A problem of will, of love of sin, of fear of cost, of pride, of family. The apologist who responds by ramping up the argument has misread the moment.

Four moves for this case.

Name what is happening, gently. I do not think the obstacle is in your head anymore. I think you know it is true. I wonder what it is costing you to keep saying no. Done with love, this can break something open. Done with judgment, it will close the door.
Ask what the resistance is actually about. Sometimes the seeker can name it, a relationship, a habit, a fear of disappointing family, a fear of being a fool, a memory of being hurt by the church. Once it is named, it can be prayed about, walked with, addressed directly.
Pray with the seeker, not at him. Can I just pray for you right now? You do not have to say anything. Out loud, simple, short. Ask the Father to make Himself known to this specific person, in this specific resistance. Pray with the seeker's permission.
Stay in the relationship. This is the case where Move 6 (stay with them after, Lesson 5.3) matters most. The convicted-but-resistant seeker often comes home weeks or months or years later. He almost always comes home through the apologist who did not give up on him.

Reflection questions

Of the three teachers, Koukl, Keller, Lewis, which approach fits your natural voice best? Which is most foreign to you, and therefore most worth working on?
Write your ninety-second gospel. Time it. Was it under, at, or over? What did you have to cut? What did you almost forget?
The Columbo method puts the burden of proof on the seeker rather than on the apologist. Why is this disarming? What is the temptation, for the apologist, to refuse to ask the question and just keep arguing?
The convicted-but-resistant case is described as "human, not tactical." What is the temptation, for an apologist, to keep arguing against a wall of will? What does that temptation tell you about how you have been formed so far?
Keller says show the cost of the seeker's own position. What is one cost of modern naturalism that the seekers in your life have probably not noticed? How could you raise it gently?

Practice exercise

Three drills. Run them in this order over the course of a week.

Drill 1, Columbo. For three days, in every conversation you have about anything contested, force yourself to ask Koukl's three questions before stating your own view. What do you mean by that? How did you come to that conclusion? Have you considered...? Notice what happens to the conversations. Notice what happens to you.

Drill 2, the ninety-second gospel. Write yours. Record yours. Listen. Adjust. Deliver it five times out loud, to your reflection, to a believing friend, to the empty room. By the end of the week, it should feel like speech.

Drill 3, the convicted-but-resistant role-play. Find a believing friend. Have them play someone who knows the case is true and will not come, and to push back gently against every argument you offer. Hold the four moves (name it gently, ask what the resistance is about, pray, stay). Notice how much harder this is than an apologetic exchange. Notice how much more it requires of you. Debrief together.
