This series began with Paul’s fear, that minds would be corrupted from the simplicity that is in Christ. We have spent twenty-nine days examining what that simplicity is, what has been added to it, what has been substituted for it, what genuine receiving of it looks like, and what it produces in the life of the person who genuinely receives it.
Today, the penultimate day, I want to give you the most practical tool this series can offer. Not a theological argument. A test. Ten specific, scriptural, honest questions that you can bring to any version of the gospel you have been given, and that will tell you whether it is the four sentences Paul declared were of first importance, or whether something has been added alongside them.
And then, at the end of this post, an announcement. Something I have been building toward since the beginning of this series. Something the content of this platform has been leading to. Something that takes the question underneath everything this series has raised and gives it the complete answer it deserves.
First, the ten tests.
Ten Tests for the Gospel You Have Believed
Test One: Does the gospel you have believed begin with the holiness of God?
The simple gospel does not begin with you, with your needs, your purpose, your destiny, your potential, or God’s wonderful plan for your life. It begins with God, specifically with His holiness, the absolute moral perfection of the one against whom sin has been committed. Isaiah 6:3. 1 John 1:5. Revelation 4:8.
If the version of the gospel you have been given began with your felt needs; your loneliness, your purposelessness, your emotional wounds, your financial struggles, without first establishing the holiness of the God whose standard has been violated, it has not started in the right place.
Test Two: Does it name sin specifically, before it names grace?
The gospel diagnoses before it prescribes. It names the disease before it offers the cure. Specifically, it names sin not as weakness or woundedness or cultural disadvantage but as the specific transgression of the moral law of the holy God. Romans 3:23. Romans 6:23. Jeremiah 17:9.
If the version of the gospel you have been given offered grace without first naming sin, if it told you that God loves you without first telling you what you are that requires that love to take the specific form it takes, it has not named the disease it is claiming to cure.
Test Three: Is the cross presented as a substitution, not merely a symbol?
The cross of Christ is not primarily an inspiring demonstration of self-giving love. It is not primarily a moral example of courage under pressure. It is the specific judicial transaction in which the Son of God bore in His body the specific penal consequence that divine justice demanded against human sin. 2 Corinthians 5:21. Romans 3:25. Hebrews 9:22.
If the version of the gospel you have been given presented the cross primarily as an inspiring symbol, as the ultimate demonstration of how much God loves you, without specifying what the cross was doing in terms of substitutionary atonement and divine justice, it has missed the center.
Test Four: Is the resurrection presented as necessary, not merely triumphant?
The resurrection of Christ is not primarily the triumphant happy ending to the story of the cross. It is the Father’s specific judicial declaration that the sacrifice was accepted, the debt paid, the penalty satisfied. Romans 4:25. 1 Corinthians 15:17.
If the version of the gospel you have been given presented the resurrection as a wonderful bonus, as the proof that God is powerful, or as the grounds for emotional encouragement, without connecting it specifically to the justification of the believer, it has missed what Paul called indispensable.
Test Five: Does it call for genuine repentance, not merely a decision?
The simple gospel calls for metanoia, the genuine change of mind and direction that involves the intellectual acknowledgment of sin, the godly sorrow over it, and the volitional turning from it toward God. Mark 1:15. 2 Corinthians 7:10. Acts 2:38.
If the version of the gospel you have been given called for a decision; a raised hand, a walked aisle, a repeated prayer, without calling for the specific inward reality of genuine repentance, it has offered the outward expression of something it did not first call you to genuinely possess.
Test Six: Does it present faith as fiducia, personal trust, not just assent?
The faith that saves is not mere intellectual acknowledgment that the facts of the gospel are true. It is the full personal entrusting of the soul to Christ as the complete and sufficient ground of standing before God. Acts 16:31. Ephesians 2:8-9.
If the version of the gospel you have been given presented faith as the agreement that Christianity is true, as the intellectual acceptance of the historical claims, without calling you to the specific act of resting your entire eternal weight on the finished work of Christ alone, it has offered notitia and assensus without fiducia. And only fiducia saves.
Test Seven: Does it offer assurance grounded in the Word, not merely in feeling?
Genuine assurance of salvation is grounded in the declared Word of God about the condition of those who genuinely repent and genuinely trust in Christ, not in the emotional temperature of a spiritual experience. 1 John 5:13. John 5:24. Romans 8:16.
If the version of the gospel you have been given produced assurance that depends on sustaining the feeling, that feels strong in the worship atmosphere and anxious in the ordinary Tuesday, it has grounded your confidence in something that fluctuates rather than something that holds.
Test Eight: Does it present Christ as the only and complete mediator?
The simple gospel presents Christ as the one and only mediator between God and man, the one through whose blood every believer has direct, bold, unimpeded access to the Father. 1 Timothy 2:5. Hebrews 10:19-20.
If the version of the gospel you have been given requires any additional human mediator; a sacramental priesthood, an apostolic authority, a prophetic intermediary, it has added to the sufficient mediation of the one Mediator the Scripture names.
Test Nine: Does it present the finished work as sufficient?
The finished work of Christ; His perfect life, His substitutionary death, His bodily resurrection, is the complete ground of the believer’s justification. It does not require supplementation, continuation, or ongoing application through any human mechanism. Hebrews 10:14. John 19:30.
If the version of the gospel you have been given presents the finished work as requiring ongoing human cooperation; ongoing sacramental participation, ongoing prophetic confirmation, ongoing seed-faith giving, to maintain the standing it purchased, it has declared insufficient what the Son of God declared finished.
Test Ten: Does it call you to surrender, not merely to add?
The simple gospel does not invite Jesus into your existing life as an additional benefit. It calls you to surrender your existing life to the Lordship of the one who purchased it at the cross. Luke 14:27. Mark 8:34-35.
If the version of the gospel you have been given presented Christ primarily as a supplement to your existing life, as the God-shaped addition that makes your existing purposes and pleasures more meaningful, without calling for the specific surrender of those purposes and pleasures to His Lordship, it has not proclaimed the kingdom of God. It has offered a service.
Ten Tests Applied to One Life
These ten tests are not meant to produce despair. They are meant to produce clarity.
If you have applied them honestly, to the version of the gospel you received, to the community that gave it to you, to the assurance you have been resting on, and found that the gospel you received passes every test, then let the examination deepen the assurance rather than diminish it. The Spirit is at work. The foundation is genuine. Rest in the finished work of Christ and press deeper.
If the examination has revealed gaps, if the version of the gospel you received failed one or several of these tests, and if that failure explains something about your spiritual experience that has never quite made sense, then the examination is not the end. It is the beginning.
The simple gospel is still available. The finished work has not changed. The prodigal’s father is still watching the road.
And now, before this post ends, the announcement I have been building toward since Day 1.
What Is Coming Next
This series has been answering one question.
What is the gospel?
Four sentences. Of first importance. Sufficient. Complete.
But underneath that question, woven into everything this series has examined, pressed upon by every false gospel we have identified, raised most urgently by the charismatic and NAR world’s claim that the Word needs ongoing supplementation, is a second question.
Why do we believe the Bible?
If the simple gospel is grounded in the Word, if the four sentences come from Scripture and are authenticated by Scripture and are sufficient because Scripture declares them sufficient, then the question of the gospel’s authority is ultimately the question of the Bible’s authority.
Why do we trust it? What grounds Sola Scriptura? How did we get the 66 books? Is the canon closed? What about the attacks, the claim that the Bible has errors, that the church gave us the Bible and therefore stands over it, that ongoing revelation supplements it? And why, personally, from the inside of a life that spent nearly four decades inside communities that systematically undermined the authority of the written Word, do I believe the Bible?
That is the question the next book answers.
Announcing: Why I Believe the Bible
Why I Believe the Bible: A Personal Defense of Sola Scriptura
The Final Convergence — Book 3
Available now on Amazon.
This is the most personal book I have written. Not merely a theological defense of Sola Scriptura, though it is that, rigorously and comprehensively. It is a testimony. The story of how a man who spent nearly four decades inside communities that systematically supplemented, undermined, and practically replaced the written Word of God, through prophetic revelation, apostolic authority, and experiential confirmation, came to rest on the Word alone. And what he found there.
Five parts. Twenty-five chapters. Two appendices.
Part One — From Voices to the Voice — My personal journey. Named communities. Real experiences. The specific moment when the Word of God stopped being one voice among many and became the voice. This section is unlike anything I have published before.
Part Two — What Is Sola Scriptura? — The doctrine defined. What the Bible says about itself. The authority, sufficiency, and clarity of Scripture. How we got the 66 books and what the canon’s closure means.
Part Three — Answering the Attacks — Eight specific objections answered: the Bible has errors, the church gave us the Bible, tradition is co-equal with Scripture, the Spirit speaks beyond the canon, Sola Scriptura is self-refuting, the Bible was written by fallible men, we need living apostles, and everyone interprets it differently anyway.
Part Four — Why I Believe: The Positive Evidence — Fulfilled prophecy. Archaeology confirming Scripture. The unity of 66 books across 1,500 years with one coherent message. The witness of transformation across twenty centuries.
Part Five — Living Under Scripture Alone — What Sola Scriptura looks like in practice. Scripture and the true church. The call back to the Word.
This is what the three-book series has been building toward:
Book 1 — What Is Truth? Truth exists and is knowable in a post-truth world. Book 2 — The Simplicity of the Gospel The content of that truth, the simple gospel of Christ. Book 3 — Why I Believe the Bible The source and authority of both, the Word of God alone.
The series of The Simplicity of the Gospel is now complete. The foundation is laid. Tomorrow, Day 30, the close of The Simplicity of the Gospel, the launch of Why I Believe the Bible, and the announcement of what the next thirty days on this platform will look like.
