New book and film to mark 25 years.
As SermonAudio celebrates its 25th anniversary, we are pleased to announce The Story of SermonAudio. This full-color book chronicles the history and heart behind the site, while the accompanying short film brings that story to life through visual creativity. Both will premiere in December 2025.
This is not the story of a website but of a work far greater. The story is a testimony to the faithfulness of God who has ensured that the voice of preaching will not be silenced, and that its witness will reach the nations until the end of the age.
What makes this film remarkable is not simply its subject, but its method. Much of it is being crafted through the use of artificial intelligence—a bold experiment in storytelling that mirrors the very tools SermonAudio itself has harnessed for gospel use.
David Astudillo is the mastermind behind this cinematic production and is also responsible for the incredible original score.
The production of the film has not been a conventional process. It was not made with large crews or lavish budgets, but in the spirit of SermonAudio itself—lean, prayerful, faithful, dependent upon grace. In the stillness of late nights, David worked frame by frame, scene by scene, sculpting something both ancient and new. The same patience that shaped code and servers now shapes motion and sound.
The result is not a marketing piece nor a documentary in the ordinary sense. It is a work of art. A story with a message. It is less about a company and more about a calling.
In the end, the film is not meant to replace the book, but to introduce it. It is part of the same mission in a new medium. A visual echo of the same refrain: “faith cometh by hearing, and hearing by the word of God.”

The book traces the remarkable journey of how SermonAudio began with a young boy in the 1980s who fell asleep each night listening to cassette tapes of preaching—a simple beginning that would, by God’s providence, grow into a global platform reaching millions. It captures the vision, challenges, and moments of faith that shaped the mission: the preservation and propagation of preaching.
Along the way came many trials and turning points, closed doors that became new directions, cyberattacks that threatened to undo the work, and seasons of deep discouragement met by unmistakable provision. From unexpected gifts that made The Vault possible to the surprising arrival of advanced hardware and expertise at just the right time, the story is filled with evidence of divine help at every step.
