I don't think it's a basis for faith at all. Faith is a reaction to our lack of knowledge and experience. It's not a product of our knowledge and experience.
Faith is absolutely a product of knowledge and experience,indirectly,it may not be a present knowledge or experience,but it certainly is based on passed knowledge and expereince, otherwise, how would we ,deposit money in the bank,eat at a restaurant, parachute, drive a car etc. if it were not based on a past expereince and past knowledge.
Mind you ,we assume a whole lot in most, if not all instances throughout a given day, without actually having the immediate knowledge to support the facts that our money is safe or our food at our favorite diner is not toxic.
However people want to look at it,we do operate in faith for our very existence.
The question is ,why is it so difficult for many to comprehend that God would ask us to have faith in Him, I mean,if we operate in faith on a daily basis,it's no wonder he says, without faith in God it's impossible to please him.
So ,we all have the ability to have faith in him because we have faith in pretty much every facet of our lives.
So faith really is a assumption,guess,having confidence,trusting in what our past expereince was.
If my breaks failed one day,I think I would be more conscious of checking them more often,even though they failed ,I still won't check them every time I drive ,that would be an inconvience,so I walk out faith again,and again,and again.
