It is definitely unreasonable for you to have inferred... that I had implied revelation “apart from the scriptures and the working of the Holy Spirit”.
Your statement appears to be a contradiction. Either you receive specific instructions from God or you don't except for what is in scripture guided by the Holy Spirit.
That is not correct. For instance, there is the principle (let’s call it Prov 3:6, “...in all thy ways acknowledge Him, and He shall direct thy paths.”, i.e., the scripture and the Holy Spirit); and then, there is a subset of that principle (the actual, particular, guidance, e.g. “Father, it is raining very hard, in sheets. Should I take the freeway ahead, or stay on surface streets?”, i.e., the specific instructions aspect) That is where learning to hear the voice of the Lord looms very large (as little Samuel had to; and as some say is not possible today because it has ceased). Because in praying that way, even “on-the-fly”, I am acknowledging His higher thoughts and ways and asking to be let in on enough of it to be of very down-to-earth, practical value — particular wisdom in an enigmatic situation, where I in my own devices might choose wrongly.
And, since we know He is there, and since He encourages us to ask, and He cares what happens to us, why not? Plus, it’s exhilarating and fascinating to communicate with God and to hear from Him. It’s addictive, in fact. But it does require some practice (Hebrews 5:14, for instance, speaks to this).
