I loved Karen Armstrong's 'A History of God' anna and it helped me understand the context of the Hebrew prophets and the Old Testament. Judaism had a far harder start than Christianity or Islam in that, coming in during the Bronze Age in the Middle East it was establishing monotheism amongst the most advanced peoples on earth at the time. I had never considered that side - history - in understanding the strategic choice of the Middle East for Abrahamic monotheism. to me, a muslim where the Hajj pilgrimage is one of the 5 pillars, I considered the birthplace of Abrahamic monotheism to do with geography. but the Middle East was called the cradle of civilisation because before the Ancient Greeks, the Chinese, the Indus valley peoples, the people of the Middle East were already building cities, creating writing, practising animal husbandry, had social hierarchy, etc. so the complexity and the philosophical nature of the Old Testament to me was because of its setting and environment at the time.
"So much time and energy goes into arguing and analysing closely or not close enough into the books,"
thats to explain it non emotionally to people outside of the faith. within the faith religion is guidance, succour. its not about natural selection, how the earth was created etc. Its not about filling in the gaps to explain why things happen, as a placemarker for science later on.
religion is about the extending the social ties of kinship out to non family, strangers, its about laying foundations down of trust. cooperation. the attraction of monotheism to those early bedouin was that belief in the oneness of God led to the belief of the oneness of people. Unity of God, Unity of man. God stands as surety over each human being, either to reward for doing good between each other or to avenge for bad done between each other, it doesnt matter about the usefulness or status of the individual who asks for help, or their ability to reciprocate back. belief in an All Seeing All Knowing God meant that the action of helping and supporting is not lost but recorded in ones book of deeds as a good action. religion made trust grow between large groups of strangers from different tribes, ethnicities, family groups etc because of a common belief, and that was seen as more important than race or class or status.
some people only join religion for social benefits. having a larger group of people to share food and shelter with and watch your back and who can help you in difficult times. not based on blood or language ties but on rituals and belief in the One God, not just the poor, the weak, but lonely people, or people without the membership of a strong warrior tribe (then) or a rich noble family with lots of connections. religion persists in the modern age because of this.
and of course, religion is a great crutch to me as an individual. it helps make me self sufficient because a large part of my emotional security is based on God, not people etc. it most benefits when there is little to no hope, or change. its closest example in secular terms is Acceptance and Commitment Therapy. as i grow older, this is what draws me most to my religion and keeps my faith. islam - peace through submission to the will of God - is about accepting, committing, and persevering when there is difficulty, pain, boredom, holding firm on values and knowing that even if no one cares, God cares, God watches, God comforts. God guides. Thats the spiritual emotional side for me of faith.
