Explain where you get these "laws of reality" from?
The same place you do - from science.
They can't be discovered empirically,
That is, in fact, exactly how they are discovered.
so how do you justify your belief in them?
I suspect you are committing the very common presuppositionalist fallacy of confusing natural laws with the reality they describe.
Laws are formulated by people. I don't know that the reality they describe 'comes from' anywhere, or what that even means.
You're wrong on several accounts.
We'll see about that.
God created the world and all it's workings and it belongs to him. If this is the case I don't know how we could call his miraculous works a "violation" of natural law as if he was somehow held accountable to a law outside of himself.
Furthermore, the God of the Bible is the immediate cause of every event. There are no mediate natural laws that stand between him and creation.
You've just confirmed my point, except you've described it here even better than I could. The entire concept of 'natural law' is utterly incoherent in your worldview. You can't even meaningfully describe a uniformity of nature, let alone appeal to one in deriving information about your surroundings. All you'd actually be describing is the emergent actions of this purported deity, which you cannot possibly predict with any measure of reliability.
What makes you think that there are such things as natural laws?
Science textbooks.
And what is a natural law?
A description of the behavior of the universe.
Again, you're conflating the laws with the facts they describe.
Further still the belief is not based on the "whims" of God but on the promises of God. God has promised to uphold the world so the belief in a consistent universe is part of the larger belief in a trustworthy God.
Even if I allow the existence of this god, you have no workable epistemological means for discerning that he has made promises to you.
Even if I allow the existence of this god and that he has made promises to you, you have no workable epistemological means for discerning
what those promises are.
Even if I allow the existence of this god, that he has made promises to you, and that you've discerned what these promises are, you have no workable epistemological means for discerning whether or not he is lying.
Even if I allow the existence of this god, that he has made promises to you, that you've discerned what these promises are and that you've discerned that he is not lying, you have no workable epistemological means for discerning whether or not he's actually capable of fulfilling his promises.
These are a few of the many,
many problems you'll have to overcome before I can 'co-opt' your worldview, even in principle (which I still wouldn't).
