What do you mean, the implications of having a saving faith?

I don't see how this is about predestination. The argument I am trying to articulate comes from the book warranted Christian Belief. The argument is basically if our minds are the product of survival of the fittest there is no reason to believe they can grasp truth, but if we are God's creatures it is reasonable to think he made our minds to grasp truth.
