You apparently regard yourself as a very knowledgeable atheist, and perhaps you are. You regard your arguments as logical, but I regard atheistic reasoning as patently and recklessly illogical, so I must disagree with that assessment. Trust me when I say I do not fear your "logical arguments." I think you have no conception of how genuinely weak, epistemologically speaking, I find atheistic rhetoric, yours included. That's not meant as an insult, nor am I disputing your basic intelligence - but you are, as they say, backing the wrong horse.
Additionally you completely misread me in regards of having my "preconceived ideas and ideals tested." Friend, I know this will likely come across as false bravado and hutzpah, but you simply lack the ability to genuine challenge my worldview. That's not a slander against you, rather, it is a candid acknowledgment that at this stage of my life, as an old man 45 years in the faith I've pretty much read it all and heard it all from the "no-God" crowd. You are neither novel nor profound, to my view. Don't read that as condescending or mean-spirited, but rather read it for what it is - a confession that I've had exhaustive contact with intelligent unbelievers over a long life and my faith is still very much intact. If I were fearful about my faith, or uncertain, or otherwise tentative in my understanding and experience of God, I would not be here. I am not some 20-something idealist who recently latched on to Christianity in novelty and new-found enthusiasm. I suspect I've written about, talked about, read about the foundational issues relative to the existence of God far more than you, and WAY more than the average YT atheist. Not brag, just fact. If your image of me is something like an uncertain, nail-biting, very persuadable and weak Christian, you may want to move along and find one of those. That is NOT me.
You ask if I have a "logical explanation for God." I do not believe God is known by logic, but that said, I do believe any attempt to establish He does not exist is patently illogical. I do not base my faith on such things, but it's my view that God must exist due to the impossibility of the contrary. A spontaneous ex nihilo, godless, uncreated creation is to me the pinnacle of illogical, misguided (and emotional) foolishness. It is evidence of much deliberate blindness. Whatever excuse you drum up for not believing in God and His Christ from Scripture and as a Christian, you have NO excuse for pretentious atheism. In that regard, I redirect you to Romans 1. I know you are being serious, and I know you are persuaded of your own rhetoric, but when I read something like this below, I can only shake my head in sadness (or amusement!):
"I am trying to see what makes you tick David, with some strong logical arguments, which as an Atheist I have an unlimited supply of, but as a man of faith, you don’t… After all, you haven’t even got a logical explanation for God, have you"
