There's humility, and then there's lethality. Sure, I could be "humble" and believe that everything worked according to the plan of a deity without proof, but not only would I be humble, I would inflict great harm upon others by spreading a belief that runs contrary to the advancement of science, vaccines, prosthetics, and just about anything else you use on a daily basis.
If a God wanted us to learn and display humility, he would presumably choose a method that would not force each individual to choose between the welfare of humanity and their personal reward.
