With all due respect this article is quite poorly written. There's a number of grammatical errors and typos which make it difficult to follow, and it's very "rambly" in its discourse.

I'd invite you to consider something very simple - is it better to have faith in something or to be convinced of it? The former could be considered a subset of the latter. Faith is blindly believing in something without necessarily being thoroughly convinced by it. In my opinion, this is a weaker position than rigorous scientific evidence or even intuition. Faith is not the same as intuition - it relies on surrendering to another perspective completely without any reservations, and has led to a great deal of evil for humanity at large (the Catholic Church has been a source of some of this evil).
