I think with age one is able to grasp abstract concepts much better......
try to evaluate this from Piaget's stages of cognitive development learning & you'll know exactly what I mean.... then contrast it with religion
.
Also there is a sound teaching used in Rudolph Steiner education (even though he aligned with nazism and theosophy so many of the families involved could be effected by the occult) about the development of a Human child. But particularly that part which is found in other cultures about the way in which children learn.
Children learn based in physical activity only until the change of teeth, from between 7 and 8.
From that time they learn based in emotions.
Then from around 14 children begin to be able to learn with their intellect of active mental processes.
Then another seven years later and the body changes again enabling the adult to accept further responsiblity; the another seven years and the person is able to experience respsonsiblity in expressing their lessons more openly in society.
I read somewhere about the teaching of Islam as to what is accomplished at ages 40, and up, going up in units of ten years. But since I am only 38 that much is really beyond me to teach.
However, if you are yourself young, then comprehending the nature of how age effects the experience of Religion is better learned by relating to the age group below that you are now in. Try even contemplating how to express to a younger person what it is like to be a bit older, and when you find you can not you might understand how the Religious experience changes with age. There is a sound biologicial basis.
Also; about that post clearly telling what age the Prophets were when they received their message: it is best to properly contextualise their experience.
Noah was old because when he was younger the flood was not happened yet.
Ibrahim was young because he needed to be prepared young, and clearly lived among those whom were able to believe a fifteen year old.
Mohammed was the right age to receive full comprehension of Qur'an and all other ahadith. But also we can know that all the Prophets, Peace and Allah's blessing go with them all, were enabled by good childhood preparation, and the exact experiences which they needed to comprehend reason in the message Allah needed for them to express. The reality of this fact is that all of the Prophets would have experienced the Prophesies being transmitted through their being as a magic-like comprehension of why all that has happened in their life has been. So each one of necessarily began to experience what is necessary for a Prophet right from birth. Each instance of any Prophesy connects many moments in time and space, and will have necessarily been connecting the Prophet with their own childhood experience as well as the future. Also within the same framework of Allah's will over long stretches of time, each Prophet connects with others in an enduring legacy.
When you study any material, like the simple question of what impact age has in the general experience of Religion, try studying that material in a field of perception lower that you, and then also a field of perception higher than you. Studying what ages different Prophets receive what messages will help. But perhaps also studying the life cycle of an Elephant could help.
