In reading the "new atheists" Richard Dawkins and Sam Harris, it is easy to see that they wholeheartedly accept the false understanding that Christian faith is an illogical leap taken contrary to evidence and reason. It's hard to blame them, perhaps, because even many Christians fail to recognize that the biblical portrayal is just the opposite, to wit, that a step of trust (in Jesus Christ) is the uniquely reasonable response to a right understanding of the evidence from reality.
The traditional Christian understanding of saving faith involves three aspects, notitia, assensus, and fiducia. Notitia means accurate knowledge, which comes through our senses, our reasoning, and revelation. Included in notitia, of course, is a right understanding of the human condition--created in the image of God and yet fallen--and of the unique solution in the incarnation, death, and resurrection of the Son of God. Assensus is the necessary agreement with that accurate knowledge. And yet, having both of these components--accurate information and agreement with those facts--is not enough. The third aspect, fiducia, means making the only reasonable response, committing one's life to that eternal Creator and personal Savior, Jesus Christ. Rather than a blind, irrational leap of faith, Christianity represents a logical step of trust, the only sensible personal response to the sum of the evidence and reason about the reality of our universe and existence.
