Not an obligation, it just seems irrational to believe something entirely unevidenced, especially when it leads one to deny other, well-evidenced beliefs.
Just what is this wisdom based on?
So you have to believe it before you can understand it? Isn't that sort of putting effect before cause; the cart before the horse?
But, historically, when has this ever produced a consistent answers? People have been 'practicing' for thousands of years, yet today there are more religious differences, and more interpretations, than ever before.
No, I suppose not -- but a faith-based answer is unevidenced by definition, so does the believer have anything non-imaginary to impart to begin with?
Does majority of people really understand quantum mechanics?
If they don't, how it comes they believe the several claims such a theory publishes every day?
When you believe in something you don't need evidence. The wife of a dude claims she is faithful and the husband believes her for what she says. No need of evidence.
Religion works different than science. With religion first is belief, later is understanding. An example if the book of Acts, where the apostles found themselves in trouble. The converted Jews were saying that converted gentiles are not fully believers because their lack of circumcision.
The job of the apostles was just to announce the good news, the dead and resurrection of the messiah, his life and words. It was not their job to teach the law.
Then, they just make the agreement to tell the gentiles who became believer of their faith, to stop doing idolatry and other pagan practices. But, about the other teachings, including the law, gentiles can go to the synagogues on sabbaths.
Notice that first was to spread out the good news, and second the new believer going to learn the doctrine.
Receiving the good news is not enough. If you never knew about the Bible and someone announced you the life of the messiah, his teachings, the promise of another body which will last forever, and you like the idea and said you want to be part of it, then you must go to a place to learn and understand everything, everything from the very beginning.
Then, in that place you will learn the books that contain the doctrines, starting with Genesis.Many new believers from the apostles times didn't know anything about Genesis, exodus, etc. But, the words of the Messiah include the mention of events read in those former books.
Here is why, the new adepts were in need to learn more, so they can understand better the good news.
Today, in science you also find lots of beliefs. Multiverses, dilating time, black holes, the world coming from a microscopic particle that exploded, millions of years of life on earth, and so forth. Those are just beliefs. There is no solid evidence for those. Even for criminal law, circumstantial evidence is not evidence.
This is why imagination took control of the theories of science, when knowledge was set apart. Look at the theories, first is the belief written in a piece of paper, then is the observation based not in impartial conclusions but forced conclusions to make the numbers and symbols fit with what is observed.
And worst, relativity and quantum weren't compatible. Even Einstein died trying in vain to make them fit one with the another.
Why those theories are working together today? The answer is very simple, manipulating one symbol here and one equation there, the discordance problems gone. Just manipulation of numbers solved the problem. And people believe those because their lack of knowledge in physics.
