This statement is as good as the statement of a young child who says to their parents: I don’t need your guidance in my life. I want to experience everything so that I can accept it. Is that statement detrimental to the child or to the parent?
Those who believe in revelation, do not consider it as an entity that replaces science, mind and experience, but rather consider those items as limited and alongside experience and the faculty of thought, revelation provides benefits that adds to the other tools necessary to know oneself and the truth of the matter.
Anyone who pays no attention to revelation and relies solely on science and their own mind will deprive themselves of many matters relating to our existence.
With regards to their destiny, they have no insight in to life after death and are completely oblivious to facts revolving around the end of this existence.
There are many secrets to the world in which we live in and if one limits themselves only to science and thought, they will oppress themselves from that knowledge.
If a producer of goods provides us with information on how to use that product, should we turn around and tell them that we are in not need of your information, and that we want to experiment with the product our self so that we can use and understand it?
The Creator of this world, with regards to its very existence, the future, goals and proper use of the environment, has provided us with information to benefit through the best of people, who are the prophets. Ignoring these divine prophets will deprive us of a much wider scope of knowledge, than those limited to simply the power of experimentations and trial and error. There is no oppression greater upon ourselves than closing our eyes and ears to part of knowledge that is available to us.
