Our Mission

Reasons To Believe (RTB) exists to spread the Christian Gospel by demonstrating that sound reason and scientific research–including the very latest discoveries–consistently support, rather that erode, confidence in the truth of the Bible and faith in the personal, transcendent God revealed in both Scripture and nature. We specifically engage influencers, educators, and other leaders with our integrative creation model, while we encourage and equip pastors and all fellow believers to participate with us in our mission.


Our Core Values

  • A high view of both Scripture and science
  • Apologetics for the sake of evangelism
  • Constructive integration of all scientific disciplines and all books of the Bible
  • Commitment to application
  • Ongoing development of a testable creation model
  • Readiness to give reasons for our hope (1 Peter 3:15-16)
  • Gentleness, respect, and a clear conscience (personal and scholarly integrity)


Our History

Hugh Ross couldn’t keep his discoveries to himself. As a postdoctoral research scientist at Caltech, his enthusiasm for astronomical studies rubbed off on others. The spiritual climate at that time had been clouded by doubts over the Bible’s inerrancy, due, in part, to a perception that science contradicted Genesis. Christian friends urged him to speak and write about how the latest scientific evidence supported belief in Scripture, including its account of creation.

Hugh’s wife, Kathy, a college English instructor, made a perfect fit for a science-faith communications team. Together they founded Reasons To Believe in 1986. A small office at their church in Sierra Madre, California, served as headquarters of the fledgling ministry, where Hugh gradually developed rapport with people outside his circle of influence. At first he spoke at churches, schools, and community organizations locally, then nationally, and internationally, each time building people’s confidence that the God of the Bible and His written revelation can be trusted.

The Early Years
Several early radio and television appearances helped give RTB some visibility, and in 1989 a publisher launched Hugh’s first book, The Fingerprint of God. RTB gained a Web presence and Hugh wrote more books, but still relatively few people knew of Reasons To Believe.

An initial staff of three grew over the years to about a dozen until RTB garnered the resources to build a scholar team. Theologian Kenneth Samples brought his logic skills with him in 1997 and biochemist Fazale “Fuz” Rana made major apologetics contributions in the biological sciences when he joined RTB in 1999.

RTB’s desire to expand its reach led to forays into the print and broadcast media. The organization published resources such as Facts and Faith, Facts for Faith, Connections, Staying Connected, and currently Reasons newsletter and the New Reasons to Believe e-zine. RTB radio, which took new form (in 2001) as a weekly live webcast, Creation Update, helped others discover RTB’s message that science and faith remain fully compatible. RTB’s media team produced quality DVDs—Journey Toward Creation and Dual Revelation, among others—to help communicate the message visually. Meanwhile chapters and networks sprang up, and a global team of trained volunteer apologists multiplied RTB’s influence.

Growing in the Twenty-First Century
As Hugh, Fuz, and Ken continued to write books and articles, speak, and debate, the hunger for RTB’s message led to more scholar team additions: first, JPL physicist Dave Rogstad in 2000 and then UCLA astrophysicist Jeff Zweerink in 2005. Gradually, the team has developed its testable creation model, which they present at secular university audiences, inviting critique from researchers.

In 2003, RTB began developing online learning courses to provide Christians with practical, Bible-based, and scientifically testable evidences to support the accuracy of the Scriptures. Today Reasons Institute (and Reasons Academy for high school students) partners with Hope International University and Biola University to continue equipping believers for the science-faith discussions of the times.

Throughout the first decade of the twenty-first century, RTB extended its outreach on the web via blogs and podcasts. Always striving to show how many discoveries provide support for the Bible’s truth, RTB scholars began Today’s New Reason to Believe, a unique science-faith blog, in 2005. Later years brought Ken Samples’ Reflections (exploring the implications of the Christian worldview) and  Average Joe’s Corner and Take Two, lay-friendly, pop culture-savvy blogs from RTB’s editorial team. In 2008, the ministry launched its podcast line-up  with Science News Flash, a resource dedicated to highlighting headline-grabbing discoveries. The year 2009 saw the addition of I Didn’t Know That! (offering unscripted answers to listener questions) and Straight Thinking (logic and reason tips from Ken Samples for thoughtful Christians).

25 Years and Beyond
RTB celebrated its 25th anniversary in 2011, commemorating the event with a special edition reprinting of The Fingerprint of God and a week-long cruise conference in Alaska. RTB leadership also took the opportunity to renew the ministry’s commitment to its mission and core values and to set new outreach goals for the next few years.

In February 2011, RTB achieved one of those goals by launching the Visiting Scholar Program with the arrival of RNA biochemist Patricia Fanning. As a visiting scholar to Reasons To Believe, Patricia specialized in embryology and evolutionary development, a previously underdeveloped area of RTB apologetics. She contributed to Today’s New Reasons to Believe and other writing projects and participated regularly on I Didn’t Know That! and Science News Flash.

Skeptics and Christians alike have expressed appreciation for RTB’s work. Churches, business groups, and Christian leaders recognize the need for, and wholeheartedly endorse, RTB’s faith-affirming—often faith-igniting—ministry.

The staff at RTB’s office in Glendora, California, plus hundreds of faithful volunteers across the nation and around the world help fuel a passion for the pursuit of theological and scientific truth. Reasons To Believe exists to impact current and future leaders and influencers with new reasons from science for faith in the God of the Bible.
