Tomorrow is launch day. Not the announcement, that was two days ago. Not the personal testimony, that was yesterday. Tomorrow is the day the 30-day blog series begins, the day the book is fully live on Amazon, the day the campaign that has been building for two weeks reaches its destination.
Today I want to give you everything you need to decide whether this book belongs in your hands, and in the hands of the people around you who need it. Not a sales pitch. A clear, honest, specific account of what is inside, who it is for, and what it will give the reader who engages it with an open Bible and a willing heart.
The Structure at a Glance
The Simplicity of the Gospel is organized in four movements and six appendices.
Movement One — What the Gospel Is
The book begins not with the counterfeits but with the real. Before any false gospel can be identified, the true one must be clearly established. This section builds the complete positive case, the holiness of God that makes the gospel necessary, the substitutionary death of Christ that makes it possible, the bodily resurrection that makes it certain, and the repentance and faith that receive it.
This is not theological throat-clearing. It is the most important section in the book, because without a clear, precise, Scripture-grounded understanding of what the true gospel is, the reader has no reliable standard for identifying what it is not.
Movement Two — What the Gospel Is Not
The second movement turns toward the counterfeits, not as a catalog of theological error but as a pastoral examination of the specific ways the gospel has been complicated, supplemented, and replaced in communities that use its name. This section establishes the diagnostic framework: the difference between fruit and root, between what salvation produces and what salvation requires. Every chapter applies this framework to a different category of addition.
Movement Three — Five Systems Examined
The heart of the book. Five chapters. One system per chapter. Each chapter follows the same structure: what the system teaches, what Scripture says, and what the difference means for the soul trusting in it.
Chapter Five: Roman Catholicism — the sacramental system measured against the finished work of Hebrews 10. Chapter Six: The Charismatic Movement — tongues as evidence measured against 1 Corinthians 12-14. Chapter Seven: The New Apostolic Reformation — restored apostolic authority measured against Ephesians 2:20 and Revelation 22:18. Chapter Eight: Legalism — performance-based standing measured against Romans 4:5 and Galatians 5:1. Chapter Nine: The Prosperity Gospel and Therapeutic Self-Gospel — health, wealth, and felt-needs gospel measured against 2 Timothy 3:12 and 1 Corinthians 15:17.
Each chapter ends not with condemnation but with an invitation, a direct word to the person inside that system, offering them the simple gospel that the system was built on but has obscured.
Movement Four — The Return to Simplicity
The final movement closes the case and opens the door. Having established the standard, named the additions, and examined each system, the book returns to the place it began, the four sentences of 1 Corinthians 15, and makes the complete, positive, pastorally warm invitation to every reader regardless of their background.
This is not the cold conclusion of a theological argument. It is the ending Paul himself would have written, pointing from every complication back to the simple, sufficient, finished work of Christ and calling every reader to rest in it.
The Six Appendices
Six additional tools for the reader who wants to go further:
Appendix A — Gospel Scriptures by Theme: A comprehensive collection of passages organized around the key elements of the gospel, the holiness of God, human sinfulness, Christ’s atonement, His resurrection, repentance, faith, and assurance.
Appendix B — The Five Solas and the Simple Gospel: How the Reformation principles of Sola Scriptura, Sola Fide, Sola Gratia, Solus Christus, and Soli Deo Gloria relate to and protect the simplicity of the gospel.
Appendix C — The Gospel Proclamation Checklist: A practical tool for evaluating any message claiming to be the gospel, twelve questions drawn from Scripture that identify whether the message is presenting the four sentences as sufficient or adding conditions alongside them.
Appendix D — Study Questions by Chapter: Questions designed for personal reflection or small group use, designed to drive the content of each chapter into personal application.
Appendix E — Glossary of Key Terms: Clear definitions of the theological terms used throughout the book — justification, sanctification, propitiation, imputation, regeneration, and others, accessible to readers at every level of theological background.
Appendix F — Recommended Reading: A curated list of additional resources for readers who want to go deeper into the subjects each chapter addresses.
A Walk Through the Five Systems
Let me give you a more specific sense of what each system chapter actually does.
Roman Catholicism (Chapter Five)
This chapter does not attack Roman Catholic people. It examines Roman Catholic doctrine, specifically, the system of justification, the sacraments as channels of grace, the Mass as a continuing sacrifice, the doctrine of purgatory, and the mediation of Mary, against the specific statements of Scripture.
The chapter engages directly with the Council of Trent’s Canon 9, which pronounced anathema on the claim that justification is by faith alone, and shows that this canon has never been revoked, modified, or substantially qualified. It then places Trent’s declaration alongside Paul’s declaration in Galatians 1:8-9 and asks the question the text demands.
The chapter closes with a direct word to the Catholic reader, written not in triumph but in the spirit of the Reformers who loved the people of Rome enough to tell them what their institution was not telling them.
The Charismatic Movement (Chapter Six)
This chapter engages the charismatic tradition with genuine respect for what is genuinely biblical within it, the gifts of the Spirit, the reality of supernatural divine activity, the work of the Holy Spirit in the life of the believer. It does not dismiss the charismatic world as fraudulent.
What it examines is the specific claim that speaking in tongues is the initial physical evidence of the baptism of the Holy Spirit, and the broader pattern of elevating experiential confirmation above the sufficient testimony of Scripture. It applies 1 Corinthians 12-14 carefully, attends to the Greek rhetorical structure of Paul’s questions, and shows from the text itself what Paul was and was not teaching about tongues.
The New Apostolic Reformation (Chapter Seven)
This chapter draws on personal experience as well as Scripture. It examines the NAR’s foundational claims, restored apostolic and prophetic offices, the Seven Mountain Mandate, the culture of ongoing prophetic revelation, and tests each one against Ephesians 2:20, Revelation 22:18, and the Deuteronomy 18:22 prophetic standard.
It addresses the prophetic track record honestly, the failed predictions, the unverified healings, the political prophecies that did not materialize, and applies the biblical standard without accommodation. The chapter closes with a personal invitation to those inside the NAR who are beginning to sense the dissonance.
Legalism (Chapter Eight)
This is perhaps the least obvious of the five systems, because legalism rarely announces itself as legalism. It announces itself as holiness, as biblical standards, as the pursuit of genuine discipleship. This chapter shows from Matthew 23, Galatians 3-4, and Romans 4 what legalism actually is, the repositioning of behavioral compliance as the ground of standing before God rather than its fruit, and what it produces in the lives of the people it forms.
The Prosperity Gospel and Therapeutic Self-Gospel (Chapter Nine)
The final system chapter examines two related phenomena, the explicit prosperity gospel of health, wealth, and your best life now, and the more subtle therapeutic gospel that presents Christ primarily as the answer to felt needs without ever naming the actual need. Both are tested against the suffering catalogue of 2 Corinthians 11, the all-who-live-godly-shall-suffer declaration of 2 Timothy 3:12, and the actual content of Paul’s gospel in 1 Corinthians 15.
Who Needs This Book
Buy it for yourself if:
You came out of any of the five systems and want a clear, Scripture-grounded framework for understanding what you came out of and why.
You are still inside one of the five systems and the questions have been building, the questions this pre-launch series has been raising for two weeks.
You are a pastor, elder, small group leader, or teacher who wants a resource that makes the full case from Scripture in a way that is accessible to ordinary believers.
You want to grow in your capacity to explain the gospel clearly and test any version of it against the Word.
Give it to someone who:
Is inside one of the five systems and would receive an honest examination from Scripture.
Is searching, genuinely, earnestly, and has been given a complicated version of the gospel without knowing it.
Has walked away from the church because the version of Christianity they encountered did not match what they read in the New Testament.
Is asking the questions this pre-launch series has been asking and needs a complete, sustained, book-length answer rather than a series of blog posts.
The One Thing I Most Want You to Take From This Book
If you read only one section, read the opening of Movement One and the close of Movement Four.
The opening establishes what the four sentences of 1 Corinthians 15 actually say and actually require. The close returns to them after everything that has been examined and makes the invitation one final time.
Because the invitation is the point. The examination is in service of the invitation. Five systems are named not because naming them is the destination but because the people inside them deserve to know clearly and completely what the simple gospel actually is, so they can receive it, rest in it, and be set free by the only thing that actually sets free.
“And ye shall know the truth, and the truth shall make you free.” — John 8:32 KJV
