I liked this, from Always Ready. Bahnsen talks about how abandoning our presuppositions as to who has ultimate authority began with Adam and Eve:
The moment one abandons his sure footing in the presupposed word of God his apologetic becomes unfaithful and precarious. A vivid confrontation of that fact can be taken from the account of man's fall into sin according to Genesis 3. Even in the garden man was responsible to submit without question to God's revelation given by special word to him. Satan's strategy then (as now) was to work toward undermining man's presuppositional submission to this authoritative word from God. He began by calling the word into question (v.1) and then contrdicting it openly (v.4). The epistemological situation was thrown into upheaval when Eve began thinking that she could have a meaningful and proper understanding of reality apart from God's revelation. In that case she was free to examine what God had to say and autonomously determine its truth over against the conflicting hypothesis of Satan. She suspended thinking God's thoughts after Him in order to become the prime authority in the world of thought. Specifically, she abandoned loyalty to her Creator so as to make herself His equal (v.5), determining good and evil for herself. She took her stand as a "neutral" judge over God's hypothesis, thereby exalting her "autonomous" reason over God's epistemological necessary word. By thus usupring the epistemic prerogatives, of the Lord, she plunged the human race into the lawlessness we see ever about is in thought and behavior.
I think we all tend to do what Eve did, even as Christians. How often do we suspend thinking God's thoughts after Him, and begin to become the arbiters of truth? Just because we are redeemed does not mean we think pure thoughts all of the time. We daily need to know the Word so that we do think God's thought after Him. Those occasions when we take control of things can be very subtle.
