How do you know what the proposition "God does not lie" actually means? How do we define the terms in which the Scriptures speak?
Either you weren't paying attention, or you are being intentionally misdirecting. I stated that the Scripture's are self-affirming and do not depend upon my interpretation for their validity. By your argument, knowledge would be impossible because everything depends upon the idiosyncrasies of an individual's interpretation.
My point here is that at some point, you are making an interpretation. Unless you are content to say that we can know the propositions without understanding their content (at which point I would contend that the "knowledge" is of no value), then you have to admit that you are getting your definitions from outside the Scriptures.
Truth is not a matter of interpretation, but of imposition. God, the source of Truth, uses whatever occasions He sees fit to impose knowledge upon the mind of any given individual. But knowledge isn't created from my interpretation. At best, my interpretation grasps what is already true. Your argument sounds like the common postmodern argument that all things are subject to some limited point of view. But that assumption denies the Revealer of Truth.
David Hume rejected inductive logic: I don't. I maintain that knowledge is justified true belief. That is a) you have a good reason for it b) it's actually true (though you obviously don't have 100% certainty) c) you actually believe it. This is the classic pre-Cartesian definition.
Hume not only rejected inductive logic, he refuted it. You haven't shown a valid refutation of Hume. Truth does not depend upon psychological certainty, as you would have it. What is your standard of justification? So far all you have is "not 100% certain." In that case, I'm 99% certain you're wrong on the good reason that you haven't refuted Hume.
Then you can establish nothing except your own existence. After all, your faculties of reasoning could be wrong (eg: you could commit a fallacy and not know it). Maximal warrant on any other issue is impossible for anyone except God.
Maximal warrant can only be given by God. The Word of God is given to us so that we may know with maximal warrant. I couldn't even establish my own existence without the justification provided from scriptural propositions.
Also, you still haven't explained how senses can be ground for arriving at knowledge.
If I look at a clock on the wall, and that clock stopped at 12 o'clock three days ago without my knowledge, but it happens to be 12 o'clock when I look at the clock, then I meet all of your criteria: 1) I have good reason to believe that a clock will reflect the time, 2) it is true that it is 12 o'clock, and 3) I believe it. But the clock isn't working, so obviously my assumption about the clock working is false--but according to your definition, I have knowledge!

I don't get what is being said here, JTB--all truths are not contingent? What about the truth that Barack Obama is the current president? That's contingent, isn't it? Perhaps you are using contingent in a different-than-normal sense...
Also, surely empiricism can give us knowledge even if we cannot get knowledge of universal truths like "All dogs are of a certain DNA structure" or "Every instance of X is Y." We can still have knowledge of things that are (frankly) more down-to-earth and useful, like knowledge of what the world around me looks like, or things like that.
Contingent was the wrong choice of words.
However, empiricism does not provide sufficient warrant for knowledge, unless you significantly lower the bar for what constitutes knowledge. I reserve the term for something with maximal warrant. Obviously all sorts of empirical conclusions are worthy of my assent, but I do not know them in any strict sense.
Every time I walk into a room to turn on a light, I believe that flipping the switch will result in the light coming on. I cannot know this to be true, however, for it is possible that the circuit fails or that the light bulb is blown. Such beliefs are not unwarranted, but they do not contain sufficient warrant to be considered knowledge. To do so is to make the knowledge of assurance or justification by faith on par with my belief that a light will come on when I flip a switch in the room.
