Sea Breeze, I have thought of a number of those verses you mentioned regarding people having a spirit within them. Yes when I think of them (both when I was a believing JW and after I became a naturalist) they always perplex me when I try to reconcile what they say from the WT point of view. Furthermore, from the atheistic naturalist point of view which I now embrace they are nonsense and superstition and foolishness to me. In regard to the latter I agree with part of 1 Corinthians 2:14. In a number of places Paul says some of his ideas are foolishness to some people and I agree with that for a number of his ideas are foolishness to me.
Your drawing my attention to verses about an inner supernatural spirit within humans does not make me want to to believe in those ideas. Instead to the extent it convinces me that the Bible teaches such others with the meaning you say they have, to that extent it reinforces my idea that vast majority of the Bible is falsehood. There is no way a person can prove that the Bible is right in saying a supernatural kind of spirit is inside people. As a result, the biblical teaching of such is superstition.
The idea of an inner supernatural spirit is nonsense to me and repugnant to me. Likewise of idea of inviting the Christ or God the Father to indwell in me is also repugnant to me (including when I was an independent Christian), because to me such is a teaching of a form of spirit possession. I hate the idea of any spirit being getting inside me and controlling me, whether it be an evil spirit (such as the devil or a demon or a ghost of a dead human) or a good spirit (such as Christ or God the Father).
In regards to these concepts and some other spiritual concepts I have never been spiritually inclined and never spiritually minded. Since early childhood I have been naturally inclined to naturalism and to science. I was born with no belief in a god (even in God) and with no belief in spirits and I wish I had never been taught to believe in those concepts. To me it is utter insanity that most of humankind worldwide believes in the supernatural, including spirits. To me, to a certain degree, the concept of living among people who believe in spirits is like being a sane person locked in an insane asylum full of insane people! To me the belief of spirits is appalling. That is part of reason I reason to Christians, with me having the hope of persuading some of them to become atheistic naturalists. I have left the JW religion and Christianity and Christian congregational worship attendance because I am not of the same sort as those who are Christians (no matter what version of Christianity they believe in). - 1 John 2:19
So-called infidelity to Christian beliefs (being unfaithful to Christian doctrines; abandoning belief in Christian doctrines) is what appeals to me, such as the agnostic writings of Robert Ingersoll. I purchased a book, edited by a hardcore promoter of atheism, of many of the agnostic writings of Robert Ingersoll. It is a great book.
The main reason why I still keep many English translations of the Bible is so that I can use them to try to correct the thinking of supernatually minded Christians, so that hopefully they will become atheists.
Update: Sea Breeze, in regarding your posts about the humans having a spirit within them, I am starting to believe you are correct in saying that the Bible teaches such and that the WT in saying the Bible does not teach such. But as a result that makes the Bible seem more full of false teachings.
The concept of humans consisting of body, eternal soul, and eternal spirit which you say the OT teaches seems to me to be the essentially the same as the ideas held by the ancient Egyptians, ancient Sumerians, ancient Babylonians, and ancient Assyrians, as well as that many other ancient peoples. That concept of those ancient peoples (since the time I learned they believed in such) and in an afterlife in Sheol has been nonsense to me since the times I learned they had that concept.
