Gospel Sharing Dojo

A hundred rehearsals with the AI bring you closer to a soul than a hundred days of hesitation.

// Premise

Using frontier AI to address the moment most believers freeze: when the conversation turns to Christ. Zero-stakes rehearsal, pinpoint feedback. Equipping bold witnesses.

// Deep dive

February began with a heavy lift: shipping the entire Garden to Google Cloud Platform. Cloud Run (serverless containers) + Cloud SQL (PostgreSQL) + GCS (via django-storages) + Cloud Build CI, fronted by Gunicorn, WhiteNoise, and Docker so cold starts land in seconds, with Secret Manager holding the keys. The rest of the month went to a feature the Church genuinely lacks: the Gospel Sharing Dojo.

The Dojo runs on LangGraph + langchain-core as a team of cooperating AI agents: skeptic, seeker, hostile coworker, curious friend. Each persona has positions, prior knowledge, and an emotional arc. An Orchestrator runs the state machine and transitions; a Judge evaluates whether the witness drifts from the Gospel core; a Coach emits structured feedback after every round. Combined with MiniMax TTS (high-naturalness), Google Cloud Speech (STT, millisecond return), and streaming Gemini output, it feels like a real two-way conversation, not a turn-by-turn Q&A.

"Therefore go and make disciples of all nations…"

Matthew 28:19

// 01 · Origin

Courage = skill × rehearsal

"Next time I get the chance, I'll share the gospel for sure." This is the thing most Christians say most often and do least. Not because they don't want to, but because nothing before that one second has been rehearsed:

  • When the other person says "I believe in science," how do you keep the door open without flinching?
  • When a coworker fires a sharp question, how do you respond with both warmth and conviction?
  • When a seeker offers you thirty minutes but you only prepared two sentences, what then?

Sunday-school evangelism classes teach theology, but not how to respond when the other person pushes back. In a DTS apologetics class I heard a phrase that stuck: "Courage is skill multiplied by rehearsal." The Church has skill — but no rehearsal hall. So this became one: a Dojo, the Japanese martial-arts training pattern, ported into gospel conversation.

// 02 · Who it's for

Who this is for

  • Believers who want to share but freeze — the heart is there, the mouth isn't.
  • Sunday-school teachers / seeker-class instructors who want a rehearsal hall for their students.
  • Church evangelism training programs — pairing theory with practice.
  • Seminary students who want to internalize responses to common objections before graduation.
  • Gospel workers and missionaries — sparring before the field.

// 03 · What it solves

Turning conversation fear into muscle memory

  • Covers the most common gospel-conversation scenarios — four personas (Skeptic, Seeker, Hostile Coworker, Curious Friend) account for ~80% of real-world situations.
  • Zero-stakes rehearsal — failure is infinitely rewindable; the AI doesn't judge; no offense to a real person.
  • Real-time feedback — pinpoints which sentence drifted from the Gospel core and what could have landed better.
  • Feels like a real two-way conversation — not turn-based Q&A but streaming voice; the AI may interrupt, push back, or sit in silence.
  • Sidesteps two common traps: (1) sounding rehearsed; (2) walling things off with religious jargon.

// 04 · Key Features

Four personas × three agents × full voice

Four AI characters, each with worldview, emotional arc, and signature pushback:

  • Skeptic — "Where's the evidence? Aren't miracles just confirmation bias?"
  • Seeker — "I've been thinking about meaning lately."
  • Hostile Coworker — "You people are just trying to brainwash everyone."
  • Curious Friend — "Why do you go to church?"

Three invisible agents collaborate:

  • Orchestrator — runs the state machine and decides when to escalate emotionally.
  • Judge — evaluates in real time whether you drift from the Gospel core.
  • Coach — emits structured feedback after every round.

End-to-end voice — MiniMax TTS (high-naturalness) + Google Cloud Speech (millisecond STT) + streaming Gemini. Hands-free conversation, simulating the coffee-shop or office where the real exchange actually happens.

// 05 · Current Stage

Public beta · embedded in the Garden · early feedback

  • Feb 2026 · Launched as the "Dojo" module inside Spiritual Growth Garden.
  • Live at spiritualgrowthgarden.com — sign in and pick Dojo.
  • Four personas live; average session runs 8-12 rounds.
  • Early feedback centers on two reactions: "I didn't know I'd get pushback like that" and "the Coach feedback was sharper than I expected."
  • Currently tuning persona realism — especially tone and cultural context in Chinese conversations.

// 06 · Roadmap

More personas · Chinese tuning · mobile

  • New personas: Buddhists, atheists, older relatives, teen family members.
  • Chinese persona tuning: localized pushback patterns (Mainland, Taiwan, diaspora — each different).
  • "Replay + expert review": send a session to a real pastor or seasoned evangelist for a second pass of feedback.
  • Scenario editor: let churches upload their own gospel-conversation scenarios and train custom personas.
  • Mobile app: rehearse anywhere — on the subway, during lunch, anytime.
  • Integration with Garden's Health assessment: when the assessment flags "gospel sharing" as a blind spot, route the user automatically into the Dojo.
