About your church
Most church members aren’t truly converted.
You heard it, and now you wonder about the people in your pew, and about yourself.
Sound familiar?
Do any of these sound familiar?
About yourself
What if my conversion wasn’t real?
You felt little at the time, and you check your salvation night after night without relief.
In a discussion
Calvinism makes God unjust.
Or someone insists that Arminians believe in salvation by free will.
You don’t need more anxiety or more slogans. You need Edwards’s own words, the strongest alternatives, and the page to turn to when the question comes back.
What’s at stake
Examining your faith without rules costs more than you think
Feelings become verdicts
Edwards wrote that very strong feelings prove nothing either way. Without his rules, every mood looks like evidence.
You start judging others
He called censuring church members as unconverted “the worst disease” of the revival.
You argue with caricatures
Without each side’s own words, it is easy to answer a position the other side never held.
And the checking never ends
For some readers, self-examination becomes a loop that calls for a pastor or a licensed professional, not another test.
A different way to see it
Edwards didn’t teach believers to live in doubt.
Nor did he teach them to trust every strong feeling. He taught them to try their experience by the rules of Scripture, humbly, and to look for assurance chiefly in a life of holy practice.
He also refused to decide which of his neighbors were true Christians. The Treasury sets out his teaching in his own words and states the strongest alternatives in theirs.
Assurance is not to be obtained so much by self-examination, as by action.

“Most church members aren’t saved”
Answer
Edwards refused to “determine positively which of their neighbors are true professors, and which are hypocrites,” and called censuring church members as unconverted “the worst disease” of revival.

The kit’s method
Facts and rules, then three questions
In The Distinguishing Marks Edwards wrote that to judge a work there “are but two things that need to be known”: “Facts and rules.” The kit applies both, with three questions on every topic.
What did Edwards actually write?
His own words, quoted from public-domain editions, with the work named.
All five coresWhat does the strongest alternative say?
The Remonstrance, Arminius, Wesley, and Whitby, stated in their own words.
Cores 1, 3, and 5What is settled, and what is open?
What the evidence and the text settle, and what remains debated.

What did Edwards call “the worst disease” of the revival?
Short answer
Censuring other Christians as unconverted. He named “censuring professing Christians of good standing in the visible church, as unconverted,” and wrote: “It is the worst disease that has attended this work, most contrary to the spirit and rules of Christianity, and of the worst consequences.”
Documented factEdwards named as an error “censuring professing Christians of good standing in the visible church, as unconverted.”
Documented factHe wrote: “It is the worst disease that has attended this work, most contrary to the spirit and rules of Christianity, and of the worst consequences.”
Documented factHe described how many would, on first meeting a person, “fix a judgment of him, from his manner of talking of religious things, whether he be converted” or not.
InterpretationThis is the strongest answer in Edwards’s own writings to the claim that most church members are unconverted. He called the habit of pronouncing such verdicts the worst disease of the revival.

Common mistakes the kit corrects
“Most church members aren’t saved” is not Edwards’s counsel: he refused to decide which of his neighbors were true professors.
The Remonstrance of 1610 did not teach salvation by free will. It denied that man has saving grace “of himself.”
The acronym TULIP is a later teaching device; it does not come from the Synod of Dort.
Edwards’s “more than 300 souls” in Northampton was an estimate he offered as probable, not a count.
The kit comes from the Jonathan Edwards Today channel, with 6,290 subscribers and more than 480,000 views (YouTube data, September 12, 2026).
In fairness
Is it for you?
It’s for you if…
- you want theological precision, not slogans
- you want to examine your faith without being crushed by it
- you want Calvinism and Arminianism stated fairly
- you care about the health of your church
It’s not for you if…
- you want a verdict on who in your church is saved
- you want a quick formula that guarantees assurance
- you want Calvinists or Arminians mocked
Before you decide
Common questions before buying
“I’m not a theologian.”
You don’t need to be. Every item starts with a short answer in plain English, and the glossary defines 57 terms with the most common misuse of each.
“I already watch the channel’s videos for free.”
The videos raise questions. The kit is the reference work: it gives the source of every claim, separates fact from interpretation, and takes you to the exact page when you need it.
“Is this just a Calvinist book?”
No. It states Arminianism in its strongest form, from the Remonstrance, Arminius, and Wesley, before the Reformed answer, and it marks what remains debated.
“Will this make my anxiety worse?”
The kit follows Edwards’s own statement that assurance comes more “by action” than by self-examination. It describes scrupulosity using the International OCD Foundation and refers readers to pastors and licensed professionals. In a crisis, call or text 988 in the United States.
“248 pages is a lot.”
You don’t read it cover to cover. The Quick-Answer Index covers 48 situations with a short answer and the page to read more, and the workbook’s diagnostic suggests where to start.
“Is this the Yale edition?”
No. Edwards is quoted from public-domain editions, and the kit is not affiliated with Yale University or the Jonathan Edwards Center.
“I read on a tablet or phone.”
It is a navigable PDF: the contents, codes, and cross-references take you where they point with a tap, and the file has bookmarks. On small screens, zoom in or turn the device sideways.
