The Assurance Library · In John Wesley’s own words

When someone says a real Christian never struggles with assurance, you’ll know what Wesley actually wrote.

And what he taught on the new birth, predestination, perfection, and falling away, weighed fairly against the strongest Reformed case and read verse by verse.

Sound familiar?

Do any of these sound familiar?

About yourself

Have I doubted too long to be a real Christian?

You don’t feel the joy other believers describe, and you check your salvation again and again.

In a discussion

Wesleyans think you stay saved by your own strength.

Or someone claims Wesley said no Calvinist could be holy.

At church

Wesley taught sinless perfection.

And a friend says “once saved, always saved” means you can live as you like.

You don’t need another argument or another anxious night. You need Wesley’s own words, the Reformed case stated fairly, and the texts read slowly.

What’s at stake

Living with these questions unanswered costs more than you think

Doubt starts to look like a verdict

Neither tradition treats a season of doubt, taken alone, as proof that a person was never saved.

You argue with caricatures

Wesley objected to the tendency of predestination, not to the people who held it.

One verse ends the conversation

Romans 9 is often quoted alone; Wesley read chapters 9 to 11 as one argument.

And the checking never ends

Checking your salvation again and again may be scrupulosity, which calls for a pastor and a licensed professional.

A different way to see it

Assurance is not a feeling to manufacture, or a verdict to fear.

Wesley taught that God’s Spirit witnesses with the believer’s spirit and that the fruit of the Spirit confirms that witness. The Reformed tradition teaches that assurance rests on God’s promises, the evidence of grace, and the same testimony of the Spirit.

The Library lays out both, fairly, and reads the key texts slowly. Even at his sharpest, Wesley drew the line carefully:

I do not say, none who hold it are holy.

John Wesley, Free Grace (Sermon 128), on those who hold unconditional predestination.

“A real Christian never struggles with assurance”

The kit’s framework

The way of salvation, in four stations

Each core places its topic on Wesley’s map, in his own vocabulary, and asks three questions: What did Wesley actually write? What do the strongest Reformed sources say? What does the biblical text say when read carefully?

  1. Preventing grace

    The grace that goes before any human response.

    Core 3
  2. Justifying grace and the new birth

    Pardon and the beginning of new life.

    Cores 1 and 3
  3. Assurance

    The witness of the Spirit and the witness of our own spirit.

    Core 1
  4. Sanctifying grace and perseverance

    Growth in holiness, and whether a believer can fall away.

    Cores 3 and 4
Core 1 · §3.04 · a complete item, exactly as it appears in the kit

How can the real witness be told from presumption?

Short answer

By its fruit. Wesley described the joy that accompanies the Spirit’s witness as “a humble joy,” bringing meekness, patience, and gentleness, while a presumptuous person grows more haughty the more confident he feels. He also pointed to the marks in 1 John, such as keeping God’s commandments.

Documented factWesley asked how the joint testimony of God’s Spirit and our own is to be distinguished “from the presumption of a natural mind, and from the delusion of the devil.”

Documented factHe wrote that the joy accompanying the witness is “a humble joy; a joy that abases to the dust.”

Documented factHe contrasted it with the presumptuous man, who, the more confident he is of the favor of God, “the more is he lifted up.”

Documented factHe cited 1 John 2:3: “Hereby we know that we do know him, if we keep his commandments.”

Common mistakes the kit corrects

  • Wesley never calls predestination a “doctrine of devils” in Free Grace; the phrase is not in the sermon.

  • Wesley did not teach “sinless perfection”: he called it “a phrase I never use.”

  • Wesley did not deny election altogether; he accepted a conditional election.

  • Wesley did not say no Calvinist could be holy: “I do not say, none who hold it are holy.”

The kit comes from the John Wesley Today channel, with 3,920 subscribers and more than 275,000 views (YouTube data, September 12, 2026).

In fairness

Is it for you?

It’s for you if…

  • you were raised in or around Reformed teaching and struggle with assurance
  • you want a biblically serious alternative, examined fairly
  • you want Calvinism stated at its strongest, not mocked
  • you want to examine yourself without being crushed

It’s not for you if…

  • you want proof that Calvinists are bad Christians
  • you want a formula that guarantees assurance
  • you want one verse to end every discussion

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 60 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 an anti-Calvinist book?”

No. Reformed positions are stated from Calvin, the Westminster Confession, and the Canons of Dort before any reply, no contemporary teachers are named, and the kit marks the common ground.

“Will this make my anxiety worse?”

The self-examination is meant to be used slowly, once, as a turn toward God. The kit 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.

“Is Christian perfection presented as settled?”

No. It is presented with Wesley’s own qualifications and as debated among Methodists.

“258 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.

“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.
