Pastoral correction · unit #11
"Boice applies Paul's catalog of vices specifically to the contemporary evangelical church, indicting self-esteem preaching, televangelist fundraising, claims to special revelation, and other church practices as manifestations of the very sins Paul warned about."

Illustrations· 6
  1. hypothetical · unit #23 — Boice imaginatively reconstructs the crowd's reasoning as news of Peter's mother-in-law's healing spreads, creating vivid expectation that Jesus would continue miraculous healing ministry—an expectation Jesus will frustrate by returning to preaching.
  2. hypothetical · unit #25 — Boice creates a hypothetical internal monologue for the disciples, contrasting the small teaching audience with the large healing crowds, satirically presenting the pragmatic church-growth reasoning that prioritizes numerical results over proclamation—the exact temptation Jesus will reject.
  3. historical example · unit #29 — Boice presents John 6 as a parallel case where Jesus' doctrinal teaching drives away crowds seeking physical benefits, using Peter's confession to demonstrate that those who understand spiritual realities recognize the supremacy of Christ's words over temporal provisions.
  4. analogy · unit #38 — Boice illustrates the adult-child analogy to explain how Christians can sin without reversing their regeneration, with the appropriate response being exhortation to act according to their actual identity rather than attempts to re-accomplish what God has already done.
  5. historical example · unit #44 — Boice narrates Calvin's initial Geneva ministry and exile, emphasizing his lack of political power, financial resources, or social prestige—possessing only the teaching office and having already been rejected once—to set up the remarkable transformation that biblical teaching alone accomplished.
  6. historical example · unit #45 — Boice catalogs the comprehensive transformation Calvin's biblical teaching produced in Geneva—conversion leading to social concern, infrastructure development, educational systems, economic reform, and theological understanding of wealth—presenting the city as a historical demonstration of Scripture's power to transform culture when faithfully proclaimed.
Theological claims· 11
  1. The Inerrancy Council's work defending biblical inerrancy from 1978-1988 was important and necessary, producing creedal documents and conducting nationwide conferences to recall evangelicals to the historic high view of Scripture. unit #5
  2. The urgent issue facing evangelicals today is not the inerrancy of Scripture but its sufficiency—while evangelicals affirm the Bible's truthfulness, they functionally deny its adequacy for evangelism, sanctification, and cultural transformation, seeking instead sociological techniques, special methods, and political power. unit #6
  3. The worst condition Paul describes in 2 Timothy 3:5 is not found in the pagan world but in the visible church—people who maintain the outward form of godliness (worship, creeds, religious activity) while denying its power because they lack the Holy Spirit. unit #10
  4. Scripture is sufficient for ministry in the last days because it is God-breathed—possessing the same creative power by which God spoke the cosmos into existence—and therefore accomplishes the miracle of bringing people from death to life and from ignorance to truth. unit #14
  5. Contemporary evangelism methods that rely on demographic surveys, entertainment-focused services, and theatrical effects represent a functional denial of Scripture's sufficiency, treating evangelism as a marketing problem requiring sociological techniques rather than as a work accomplished through the proclaimed Word. unit #17
  6. Entertainment-driven church growth produces large gatherings but not genuine conversions, because while the world will come for what it wants, authentic gospel work happens only through God's converting power operating through the proclaimed Word. unit #18
  7. Contemporary churches treat sanctification as requiring psychological analysis and therapeutic intervention rather than biblical categories of sin and faith, adopting culture's language and functionally denying Scripture's sufficiency for growth in godliness. unit #32
  8. Contemporary churches approach sanctification through either legalistic formulas (Bible reading, prayer, witnessing without understanding) or charismatic experientialism (second blessing, tongues, miracles), but neither approach produces genuine holiness because both bypass biblical doctrine. unit #33
  9. Sanctification is fundamentally a matter of doctrine—poor behavior in the contemporary church results from failure to understand and mentally grasp what God has accomplished, with holy action flowing from doctrinal comprehension rather than from formulas or experiences. unit #36
  10. Political engagement seeking to elect Christians to power and impose Christian laws mistakes the function of civil government—which requires competence, not Christianity—for the church's spiritual work, confusing two distinct spheres of authority. unit #41
  11. Cultural transformation occurs from the bottom up through gospel conversion of individuals who then create laws reflecting God's law, not through top-down political power—seeking change through government makes the state an idolatrous savior, displacing God's saving work through the proclaimed Word. unit #42

0 · Boice orients the congregation to the weekend conference structure and announces the primary text, establishing continuity with previous sessions while preparing for the final message on Scripture's sufficiency

It's been a great pleasure to have the opportunity of teaching the Bible and teaching about the Bible this weekend, because that's been our theme. The text that we have used as a basis for our study is also the Scripture this morning, and we've been reading it or a portion of it for each of the preceding sessions. We read exactly this on Friday night as we started, and then we read most of it on Saturday morning and Saturday evening. So I invite you to turn to it now, second Timothy, the third chapter. We're going to read the first five verses and then skip to verse 10 and read from that point on to the end.

1 · Boice reads the primary text with an appended prayer, establishing the biblical foundation for the sermon's argument about Scripture's sufficiency in terrible times

2 Timothy 3:1 but mark this there will be terrible times in the last days. People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, without love, unforgiving, slanderous, without self control, brutal, not lovers of the good, treacherous, rash, conceited, lovers of pleasure, rather than lovers of God. Having a form of godliness but denying its power have nothing to do with them. You, however, know all about my teaching, my way of life, my purpose, faith, patience, love, endurance, persecution, suffering. What kinds of things happened to me in Antioch, Iconium and Lystra, the persecutions I endured. Yet the Lord rescued me from all of them. In fact, everyone who wants to live a godly life in Christ Jesus will be persecuted, while evil men and impostors will go from bad to worse, deceiving and being deceived. But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God breathed and is useful for teaching, rebuking, correcting and training in righteousness so that the man of God may be thoroughly equipped for every good work. And God will bless the reading of his Scripture to our minds and hearts.

2 · Boice expresses personal gratitude for the congregation's attendance and engagement, acknowledging both local members and those who traveled from distance, building rapport before the teaching proper begins

Well, I've said each time, as I began on Friday and also twice yesterday, what a great privilege it is for me to be here each time for a weekend like this at Believer's Chapel. It's a wonderful congregation to speak to. Not only attentive, but you also come to the services, especially on Saturday. We were very pleased the number that were there Saturday morning and I understand on Friday night an overflow. And that is always an encouragement to the preacher. It helps you prepare, it also helps in the delivery. And we trust the Holy Spirit has been blessing as We've studied these things together. I was also thankful to those who have come from a distance because of the Bible Study Hour, having heard it announced that I was going to be in Dallas. We had people from Fort Worth, of course, not so far to come, but from Waco and Oklahoma City and Abilene and a number of other places that I didn't get all nailed down. And I'm very appreciative to those people who came and for leaders, teachers, and those who attend the Bible Study Fellowship classes. I've been privileged to be involved with that ministry for a while, and it's always good to meet those leaders and members of the classes, too.

3 · Boice describes the mission of the Bible Study Hour radio ministry and announces expansion plans, connecting the weekend's teaching on Scripture to the broader work of training Christians in biblical thinking

We're encouraged in the work of the Bible Study Hour. Our task, as you probably know, if you hear it at all, is to encourage and train people to think and act biblically. We're very concerned that we are living in an age where there's very little truly Christian thinking going on, and we're trying to encourage that by the teaching on the radio. We have a number of versions of the Bible Study Hour, an hour long weekend worship version, the half hour version that we've had from the very beginning, and now, more recently, a daily program. And one of the reasons why Charles Morris is here with me in Dallas and has been accompanying me and other places is to see what we can do to get the daily broadcast on in other places. And so we're hopeful we can do that in Dallas. Maybe by the next time I come, we'll have the daily program going here as we have support for it and as Charles is able to raise that, that's what we'll do.

4 · Boice summarizes the weekend conference structure—Scripture as foundation, Holy Spirit and Scripture, and Bible problems—positioning the final message on sufficiency as the culmination of the series

Now, we've been talking about 2 Timothy 3, about the word of God. And although what I have done here in these days has not been, strictly speaking, an exposition of the chapter, we have started at that point to talk about the Scripture and try to deal with some of the questions that are contemporary, questions concerning the word of God and also the kind of problems that we have learned over the years that Christian people have in mind. I began by talking about the Scriptures as a foundation for individuals and for Christian teaching and for the church, and emphasize that that's especially true in our day because we live in a relativistic age where people no longer believe in truth. They have no absolutes. People are adrift. They think it's a very liberating situation because if there are no absolutes, you can do anything you want, you're absolutely free. But they don't understand that that is freedom. Bought at a tremendous price. The price is the price of significance. If you're not responsible for what you do, what you do doesn't matter. And people not really understanding what's been happening to them, are floundering and wondering why in the world they're here anyway. And does life have any meaning at all? Well, we find all of that in the Scripture because God himself, who speaks truth and clearly has explained to us in the Word what it's all about. So we have a foundation, and we began to talk about that on Friday night. And then yesterday we dealt with a couple things that are on people's minds. People are concerned with the relationship between the work of the Holy Spirit and the Scriptures themselves. It has to do with the theology of revelation. How does God actually speak to us today? And we saw that the Word and the Spirit always go together. And we spent some time just talking about a theology of revelation. Some of the key words we were looking at were inspiration. That's one of the words in this passage. We looked at regeneration, and then we looked at illumination, all things that the Holy Spirit does. And we saw that that's the way he speaks and continues to speak through the Word, doing that, bringing blessing to his people. Last night, we were dealing with Bible problems. Years ago, when I was involved in the work of the Inerrancy Council, we did surveys of Christian congregations to find the kind of problems that were in people's mind and what they would like us to deal with when we came to teach about the Bible. And that was always one of the questions, how do you deal with Bible problems? Because people are always saying today, oh, you can't hold to that old view of the Bible, that the Bible is the word of God and trustworthy. Because today we know there are all these problems and all these errors in the Bible. And so we were trying to come to grips with that last night and I hope, offered some help.

5 · Boice recounts the decade-long work of the Inerrancy Council, establishing the historical and ecclesial importance of defending biblical inerrancy while preparing to argue that sufficiency is now the more urgent issue

Now, what I'd like to talk about this morning is the sufficiency of the Scripture, because I'm convinced that that is really the issue of the moment. When we began the work of the inerrancy council in 1978, we did it with the concern that evangelical institutions, particularly the seminaries, but also allegedly Christian schools, colleges, and so on, were departing from this high view of the Scriptures that really had prevailed in the church all down through the ages. Until relatively modern times, the Church believed, and evangelicals were supposedly believing, that if God has spoken in the Bible, as we believe he has, then he has spoken truthfully. You can trust everything he says. God doesn't lie, he doesn't even stammer. And what you read here in the Bible you can understand and build a life on. But that was beginning to fade away in the evangelical institutions. And I remember Francis Schaeffer saying early on in the discussions that we had that unless something was done to recall the evangelical church to the high standards of the past, we wouldn't have an evangelical church to pass on to our contemporaries or to our children. And so we began to deal with that. And we did it over a period of 10 years. We had three scholarly conferences that produced documents that became in time almost creedal, dealing with, with the matter of authority and inerrancy itself. And then second document dealing with matters of hermeneutics, I.e. principles of interpretation. And then finally a document dealing with the application of the inerrant Bible, properly interpreted, to the great issues of the day. And along the way we also held seminars all across the country on the authority of Scripture and two large lay conferences. One out in San Diego. Bill Bright was co chairman of that conference, and then a second one in Washington D.C. and Chuck Colson was the chairman of that conference. So over a 10 year period we produced all this literature, held all these conferences defending the authority of the Bible as the inerrant Word of God. Now I think that was important. I think a great deal of very useful work was done.

Scripture's Sufficiency in Our Marriage

  1. What aspect of the sermon challenged you most—whether about how we approach Scripture's power, or where we've subtly sought other sources for answers we should expect from God's Word?
  2. In what areas of our marriage do we tend to rely on cultural wisdom, psychology, or other voices rather than returning first to what Scripture teaches about love, conflict, or growth together?
  3. How can we pray for one another this week to recover genuine confidence that God's Word is sufficient not just for our individual faith, but for the health and sanctification of our marriage?

What Would Jesus Skip?

For the parent

The sermon mentioned that Jesus chose to preach rather than do more healings, even though healing drew crowds. Help your family think about what Jesus prioritized and why. Listen for how they understand the difference between what's impressive and what's truly powerful.

In the sermon, we heard that Jesus could have done more miracles and healings to draw bigger crowds, but instead He kept preaching God's Word. If you were one of Jesus' followers and someone asked, 'Why didn't Jesus heal more people when He could have?'—what do you think Jesus would say?

Small-group discussion

6 questions for your group this week

  1. In 2 Timothy 3:1-5, Paul describes the character of people in the last days. As you read through the list of vices he names—self-love, materialism, pride, lack of self-control—where do you recognize these patterns not in the pagan world around us, but within the visible church itself?
    2 Timothy 3:2-5
    → What makes it particularly troubling that Paul says these people maintain 'the form of godliness' while denying its power?
  2. The sermon argues that the urgent issue for contemporary evangelicals is not whether Scripture is inerrant, but whether it is sufficient. What is the difference between affirming that the Bible is true and actually believing it is adequate for evangelism, sanctification, and cultural change?
    → Can you identify a specific area of church life or ministry where we might be functionally denying Scripture's sufficiency by turning to techniques or methods from the broader culture instead?
  3. Paul tells Timothy to 'remain faithful to what you have learned' from Scripture, emphasizing that the Word of God is 'God-breathed' (2 Timothy 3:14-17). What does it mean theologically that Scripture possesses the same divine power by which God spoke creation into existence?
    2 Timothy 3:16
    → How should that truth reshape the way we think about preaching or teaching God's Word in our church and small groups?
  4. The sermon references Mark 1:37-38, where Jesus' disciples urge Him to pursue the crowds coming to Him, but Jesus instead prioritizes preaching in other towns. Why do you think Jesus made that choice, and what does it reveal about His confidence in the power of proclaimed Word versus meeting people's immediate wants?
    Mark 1:37-38
    → When our church faces the temptation to make worship 'appealing' or to adopt entertainment methods to draw crowds, how should Jesus' example guide us?
  5. The sermon claims that sanctification—growth in godliness—is fundamentally a matter of doctrine: that right behavior flows from right understanding of what God has accomplished in Christ. What is the difference between trying to become holy through formulas (daily Bible reading, prayer lists) or experiences (special encounters, emotional highs) versus understanding the gospel truths that should motivate and empower change?
    → What false views of sanctification have you encountered—either in church teaching or in your own thinking—and how does the gospel address them?
  6. The sermon critiques the idea that cultural transformation comes through political power—electing Christian politicians or imposing Christian laws. Instead, it argues that real change happens 'from the bottom up' through the conversion of individual hearts. How does the gospel of Christ's finished work change the way we should think about our role as Christians in the political and social spheres?
    → What does it look like to prioritize the proclamation of Scripture and the conversion of hearts over political strategy in your own witness and community engagement?
Daily readings · Monday–Friday

5-day reading plan

This week we trace the sufficiency of Scripture across five theological claims: from the power of God's Word itself, through the church's crisis of faithfulness, to the gospel's transforming work in individuals, and finally to our call to recover confidence in proclamation over contemporary methods.

Monday Romans 1

Paul opens Romans by anchoring the gospel's power not in human persuasion but in God's self-revelation through the Word—the same Word that accomplishes salvation, from death to life and ignorance to truth. We need not supplement Scripture with techniques or strategies; the gospel itself carries the efficacious power of the all-glorious God who spoke creation into being.

Tuesday Mark 1:21-22

Notice the contrast: Jesus taught with authority because His words flowed from union with the Father and the Spirit's power, while the scribes—religious professionals maintaining the forms of piety—lacked that transforming authority. The contemporary church often mirrors the scribes' condition, preserving creeds and worship while functionally denying the Spirit's power to change hearts through the proclaimed Word.

Wednesday Mark 1:37-38

When the crowds pressed Jesus to stay and capitalize on His popularity through more healings and signs, He redirected toward His true calling: proclamation of the gospel in the neighboring towns. We face the same temptation—to abandon the hard, slow work of preaching God's Word for methods that draw crowds and feel more immediately successful. But genuine conversion happens only through the proclaimed Word, not through entertainment or therapeutic appeal.

Thursday Romans 6:11

Paul exhorts us to reckon ourselves dead to sin and alive to Christ—a call grounded in doctrinal understanding of our union with Christ in His death and resurrection. Contemporary churches often replace this mental grasping of doctrine with legalistic disciplines or charismatic experiences, but genuine growth in godliness requires that we grasp with our minds what Christ has done and live accordingly.

Friday John 6

When the crowds wanted to make Jesus king and impose His rule through political means, He withdrew and redirected attention to the true bread from heaven—conversion through faith in His Person and work. We must recover this vision: real cultural change flows from individual hearts transformed by the gospel, not from Christians wielding political power or adopting the world's methodologies to advance the kingdom.

Memory verse this week

2 Timothy 3:16-17

All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.

Why this verse: This verse is the theological capstone of Boice's entire sermon—it establishes Scripture's sufficiency by grounding it in God's very breath and demonstrates that the Word alone equips believers for every ministry and life task, requiring no supplementation from cultural methodologies or contemporary techniques. Memorizing this verse anchors the congregation in the Reformation principle of sola scriptura and guards against the functional denial of Scripture's adequacy that Boice identifies as the urgent evangelical problem.
