Religiosity can express any of various impulses, including these:
(1) Desire to placate the gods.
(2) Desire magically to assure desired outcomes. This is the essence of the Baal cult. Robert Jenson says it is also the essence of all religions except Christianity (:lol ).
(3) Desire to understand, and live in harmony with, the truth.
My earliest childhood memories are of a sense that there is more to the world than we perceive with our five senses, and of a desire to understand and correctly relate to that larger world. I have my moments or months of what some call doubt, of agnosticism or atheism, but in the end this thing always comes back. I feel it in my flesh and bones. This is ONE foundation of my religiosity.
