Koukl received an
M.A. in
Philosophy of Religion and
Ethics from
Talbot School of Theology, and also an M.A. in
Christian apologetics from
Simon Greenleaf School of Law. In 1993 Koukl founded Stand to Reason, an organization dedicated to training those supporting his Christian viewpoints to defend their faith with "knowledge, wisdom, and character". Stand to Reason produces a weekly radio program, audio podcasts, articles, and video materials. Stand to Reason ended its radio program on
KBRT, its flagship station, on 6 December 2015. Stand to Reason sponsors mission trips in which students encounter those with opposing points of view, including
Mormons and
atheists. His book "Tactics: A Game Plan for Discussing Your Christian Convictions" was cited as a must read on how to share Christian beliefs and defend Christianity in an article on the
Christian Post. Koukl is known in particular for what he calls the "
Columbo tactic" (named after the fictional detective) of always asking one more question. ==Books==
