Well, faith that something will be true before you know it's true does help with confirmation bias, so in that sense the scripture is spot on.
If you have faith in the existence of something or someone before you have absolute proof of it existing then you are more likely to look for and find evidence of proof that it exists and vice-versa. So in a sense the scripture is self fulfilling. Though you have the accounts of the famous "road to damascas" moment for Paul where no such faith (in this case jesus being the messiah) existed first, but it was Paul that was approached not the other way round so apparently faith isn't needed if a heavenly being approaches you. Sort of celestial "don't call me, I'll all you."
So, of cousre anyone is better off going into any investigation completely neutral without any pre-existing bias if their desire is to find truth not confirm wishful thinking. Pretty hard when most people have unconscious leanings in one direction or another.
Also, I understood the scripture quoted to mean that any "faith" would be in the existence of God himself not - faith in your faith in a religion. The word and concept of "faith" is bandied about willy-nilly applied to obviously and ridiculously untrue things - unfortunately.
