Art is a delivery system for worldviews.
Public education grants secular worldviews an exclusive monopoly in the classroom.
The biblical writers didn't need to say everything; they could assume some things. They didn't anticipate a day when even Jews and Christians would fall under influences of non-biblical religions, philosophies, and worldviews, to the extent that is now the case in our pluralistic culture and society.
We all construct worldviews that give us a sense of meaning. Mostly it is about belonging to a group and having a sense of identity and purpose.
