Presuppositions of Logic

At the outset of  McInerny’s opening chapter, he lists three presuppositions that undergird Logic:

 1)  The discipline presupposes our having a sensitivity to language and a knack for its effective use, for logic and language are inseparable.

2) Logic also presupposes our having a healthy respect for the firm factualness of the world in which we live, for logic is about reality.

3) Finally, being logical presupposes a lively awareness of how the facts that are our ideas related to the facts that are the objects in the world, for logic is about truth.  (Emphasis mine).

 What i found so fascinating (but not surprising) was how these presuppositions cohered so well with Christian theism.  The last two points really struck me. 

 I would like to see others thoughts here on the implications of #2 & #3.  Here are some questions to begin with, since i am eager to learn from others out there:

1) What implications are there for Christians who devalue reason (Both good & bad)? 

2) For those of us who do value reason, how does the use of antimony, and appealing to mystery cohere with #2 & #3?  Are such devices valid, and to what extent?

3) Since Christians believe that the universe is created and governed by a God of order, are Christians in the best position to reason correctly?
