Ian Paul’s post, “What does it mean to ‘love God with your mind’?” is really very good and deserves a careful and thoughtful read.
Here’s a quote from one of my favorite books in this space:
The believer is a critical adventurer, taking rationally responsible risks. If he or she takes a leap of faith, it should be a leap conditioned by criticism in its choice of alternatives and responsible for continued criticism after the leap. (p 71)
