AI & Ministry: How Truth For Life is Using Voice Cloning to Reach Millions

At the 2025 Digital Ministry Conference, leaders gathered to explore innovative ways to expand their ministry’s digital impact. One of the most thought-provoking sessions, From Text to Voice: How Truth for Life is Using Voice Cloning, featured Mike Costlow, Director of Operations and Human Resources, and Sarah Sharp, Director of Digital Communications at Truth For Life. This session detailed how the ministry used AI-powered voice cloning to amplify Alistair Begg’s reach—without requiring hours of new recordings.

Truth For Life faced a unique challenge: they had over 700 devotionals to record, but Alistair Begg’s schedule made it impossible to record so many manually. Instead of compromising quality, they turned to AI voice cloning. The result? A scalable, ethical, and authentic way to distribute biblical teachings across 190+ countries, including Antarctica.

So, what can ministry leaders learn from Truth For Life’s experience? Here are the four key takeaways from this groundbreaking session.

1. AI Can Scale Ministry Without Losing the Personal Touch

Many ministries worry that AI might depersonalize their content. Truth For Life’s experience shows that when done right, AI can actually enhance engagement. By using Theotech’s AI-powered voice cloning, they ensured that every devotional retained Alistair Begg’s unique tone, cadence, and warmth, just as if he had recorded it himself.

For ministries looking to expand their reach but facing time or resource limitations, AI-driven solutions can help scale content while preserving authenticity.

2. Transparency is Key to Building Trust

One of the biggest concerns with AI-generated content is audience trust. Truth For Life openly communicated that AI was used to generate Alistair’s voice while maintaining the integrity of his teachings.

By being upfront about AI’s role, they strengthened their relationship with their audience rather than weakening it. This lesson is crucial: transparency fosters credibility. If your ministry considers AI, ensure your audience understands how and why it’s being used.

3. Ethical Oversight is Essential in AI Implementation

Ethical concerns around AI, especially voice replication, must be addressed thoughtfully. Truth For Life took key steps to ensure their project adhered to ethical standards, including:

If your ministry is exploring AI, establishing clear ethical guidelines and approvals should be a top priority.

4. AI Opens Doors for Global Ministry Expansion

AI-powered voice technology allowed Truth For Life to extend Alistair’s teachings to places they may have never reached before. With nearly a million streams across 190+ countries, the ministry saw firsthand how AI can amplify the reach of gospel-centered content.

For ministries considering AI, this is a game-changer. Whether through voice cloning, automated translation, or AI-driven content distribution, ministries can break down barriers and bring the message of Christ to a broader global audience.

What’s Next? Steps for Ministry Leaders

AI is rapidly transforming the digital landscape, and ministries need to stay informed. If you’re considering AI-driven tools like voice cloning, here are three actionable next steps:

1. Evaluate Your Ministry’s Content Needs – Do you have content that could be scaled with AI (e.g., sermons, devotionals, translations)? Identify areas where AI can enhance—not replace—your ministry’s voice.

2. Create an Ethical AI Strategy – Establish clear guidelines, approvals, and transparency measures before implementing AI. Make sure leadership, content creators, and your audience are on the same page.

3. Stay Informed and Learn from Others – AI in ministry is still new, but Truth For Life’s experience provides valuable insights. Watch the full session and explore how other ministries are using AI responsibly.
