Balancing, renewing or gaining Faith

So I was reading about jhana and nimitta in a book by Pa-Auk tawya sayadaw here page 41 if anyone wants to read. Where I come across this: > To balance faith with wisdom, and concentration with effort, is > praised by the wise. If, for instance, faith is strong and wisdom is > weak, a person will develop faith in, and respect for objects without > use and essence. For instance, he will develop faith in, and reverence > for objects revered and respected by religions outside orthodox > Buddhism, such as guardian spirits or protective deities. **If, on the > other hand, wisdom is strong and faith is weak, a person can become > quite crafty. Without meditating, he will spend his time simply > passing judgements. This is as difficult to cure as to cure a diseas > caused by an overdose of medicine.** If faith and wisdom are balanced, > however, a person will have faith in objects he should have faith in: > the Triple Gem, kamma, and its effects. He will believe that if he > meditates in accordance with The Buddha's instructions, he will be > able to attain the pañibhàga-nimitta, and jhàna Now I do experience with the latter, too much wisdom, not enough faith. I did and must have had some faith at the beginning of my study into Buddhism, though at that time I still had faith (believed) in god (creation/christian god) but now I "know" things that I no longer have faith in, because I know and understand them I have conformation rather than faith. Even kind of complicated concepts like "faith in" karma, I no longer have faith in because I understand and can see first hand karma manifest through cause and effect. Even the Buddhas enlightenment I have "seen" so to speak as I have seen the fruits of the path so my faith in these things have waned or dissipated. There has not been any sort of scepticism about the actual Buddhas teachings for a long time, I at least intellectually understand even the most complex concepts. I remember hearing a sutta about Buddha asking a student if they have faith in the Buddha and the student replied "no I do no longer have faith in the Buddha", to which the other members of the sangha were shocked, but the meaning of the sutta was that this person had gone beyond faith and understood the dhamma so no longer had any faith in what the Buddha taught, as he had seen himself. I cannot remember if this is a mahayana or theravada sutta, and I think the student was an arhant, meaning after arthantship one no longer has faith. Still the question is before arthantship, as I myself am not an arthant. **So the questions are:** how do we then gain or renew faith in order to balance wisdom? Is there a point where faith is no longer able to manifest in ones mind before arhantship so there is no way to balance wisdom with faith? and if so, how would we [then] actually be able to balance wisdom without faith?
