Education and work
In 1993, Koukl founded Stand to Reason, an organization dedicated to training Christians to defend their faith with "knowledge, wisdom, and character". In addition to a weekly radio program, Stand To Reason delivers audio podcasts, articles, and video materials, many of which are available for free on the website. Stand to Reason is also well known for sponsoring unique mission trips in which students encounter those with opposing points of view, including Mormons and atheists.
