Reasons to Believe

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 the Great Commission.


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

Raised in a secular home and passionate about astronomy from early childhood, Hugh Ross was stirred by the theological implications of cosmological discoveries. Since the universe had a beginning, it must have a Beginner. On that basis he decided to investigate the world’s “holy books” to test them for scientific (as well as historical) accuracy and consistency. Only the Bible passed the test.

When Hugh began to share his findings with others, he was surprised to discover how many people see science as a barrier to trust in Scripture and to faith in Jesus Christ. In 1986, he and his wife, Kathy, founded Reasons to Believe, a ministry devoted to breaking down that barrier. Through the years they have assembled a team of scholars to assist in spreading the message that the facts of nature and words of Scripture point to one and the same Creator-Redeemer.
