Christians need to ask the difficult questions about the God they believe in and trust. An unexamined faith will collapse sooner or later when an unexpected difficulty comes along.
But those who are sceptical of the Christian faith also need to doubt their doubts, for every doubt has a form of faith undergirding it. This is the fourth talk in the "God we don't believe in series," responding to the clam that the Bible is culturally obsolete and historically inaccurate.
