So, you're a Deist now?
God most certainly is transcendent existing outside of the realm of space and time. He is eternally existent, uncreated, and self-sufficient. You can read this all in the theology proper section of the systematic theology of your choosing so I will not drone on about stuff you can or should have looked up and read for yourself. I am guessing that HAC probably was not too strong in their study of systematic theology except for the parts that say you ought to be out "Soul-Winning" right?
God is not only transcendent but is at the same time Immanent with his creation calling all the stars and telling them by name (Psa 147:4), knows the affairs of the least of his creation and the number of hairs on your head (Mt 10:29-31). There is nothing hid from God that he does not know that shall not be brought to light on the day of judgment (Heb 4:13).
But the one smoking gun is found in Romans 1:20 - For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
I do not have to say anything to prove this is the word of God, You know it to be true, EVERYONE knows it to be true including anyone who has never read Romans 1:20 in their life!
You give mankind far too much credit! The "god" of human worship is a god concocted up by his vain imagination and it has absolutely nothing to do with anyone sincerely searching out who is the "One True God!
Romans 1:21-23 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Romans 3:11 There is none that understandeth, there is none that seeketh after God.
John 3:19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
An "Honest Skeptic" is an oxymoron! They are searching for everything else BESIDES the truth!
God works with the limitations of our understanding using anthropomorphisms such as "The Eyes of the Lord," and "his hand is stretched out still" even though God is Spirit without parts or complexity. God commanded "No Graven Images" because of the impossibility to come up with a visible image of an invisible God!
As stated, every person KNOWS of the true and living God and that he is to be worshipped.
You are no different from anyone else who has stepped away from "Faith!" I have seen it far too many times now and it is usually a gradual slip into apostacy! It usually starts with questioning of the inspiration, authority and sufficiency of the scriptures! If they can cast doubt upon the Word of God, everything else will come crashing down around them!
KJVOs may have a flawed view of inspiration and preservation of God's word but at least THEY BELIEVE THEY HAVE A BIBLE! The problem is you let someone take your Bible from you and without it, you are unable to become wise unto salvation!
You really need to ask yourself why is there a book that was written over the course of 1500 years by over 40 different authors of differing walks of on three continents - Europe, Asia, Africa, written in three languages - Hebrew, Greek and Aramaic would be so unified in PORTRAYING ALL OF MANKIND IN SUCH AN UNFLATTERING LIGHT?
If the Bible were simply written by man according to man's wisdom, don't you think he would speak more highly of himself? Do we not see such everywhere else ASIDE FROM the Judeo-Christian Scriptures and in every other religion aside from Christianity and Historic Judaism?
