Man has a tendency to be intellectually lazy and assume just about anything about life to make it easier.
Are you living in reality?
The Almighty gave the Torah as the universal standard by which humanity can check assumptions for their validity.
Beware, false assumptions can be very costly.
“The biggest fear people have, and the one most important to overcome, is the fear of facing up to reality. People would rather live an illusion than wake up to reality. Why? Because if reality turns out to be something different than what we’re used to, it means having to change our course in life. And that hurts.” Rabbi Noah Weinberg, Aish HaTorah
