YouTuber Evid3nc3 recently put out a couple of videos that describe the development of the modern concept of the Judeo-Christian God in great detail. From what I’ve heard and read before, he really seems to know what he’s talking about; plus he has plenty of sources cited to back up his claims. If you’re at all interested in learning about how the monotheistic god of the Abrahamic traditions came to be, you should definitely watch these. It helps explain the evolution of the mythology, from the worship of the tribal war god of the Israelites as one deity among many to the theology we see today of a singular, all-powerful creator god.
Evid3nc3 also has several other great videos, including the compelling story of his deconversion.
