People have their gods. I think the wtbts god is the the product of a delusionary fear that is refined and sort of cast in stone, aside from when their god is wounded (by trueness), and then their god gives them (they give it) 'new light', because their god is light to them.
"and without Him was nothing made that was made"
As the god is made by their own, it is they that also then provide the light - it has come from within them - and some indeed identify with the projected image, but others others simply submit their mind to the other's god, in fear, for a long or short time. Courage is required for insisting upon the truth above all loss, and it is that devil is described in terms of coward.
Even within 'christianity' there are very many gods - gods that one identifies with and/or believes to be so. For some there is every aspect of loving, but for others there may be an imaginary beast of a person - eg. one like Nero (666) was in spirit - a god who would kill those who mock him, or try to take from him, or not bow down to him, or give him the due homage and respect that he and his loyal servants require and expect.
They can read the same books and say 'yahweh' and 'jehovah' and whatever, but their god isn't myne.
