“Without faith it would be impossible to eat stew”
Faith is to believe or not to believe in something on the ground of something other than objective evidence. Many of our most basic beliefs are subjective without us even realizing it. However, once accepted by faith, most believes can be given some evidence to support them. A large percentage of our beliefs are actually based on the authority of people whom we trust or have faith in. This trust represents a subjective element in the majority of things that we believe. Our beliefs can also be strangeness or weaken by inference and reason. Outside the religious spear say as in science faith might be like what we call a hunch or a vision. Hunches and visions like faith have various degrees of intensity and clarity. These degrees are as numerous as individual.
For example, my neighbor goes to post office ones a week to pick up his mail and I have faith or a hunch that he will do it tomorrow. So, my expectation of seeing him at the post office grows to almost a certitude. I could say I have faith that I will see him at the post office. If he fails to show up I begin to look for a reason. I do not say he does not exist because he doesn’t act according to my expectations.
Like my experience with my neighbor, when the Bible speaks of faith it taking about a belief based on experiencing God. This experiencing of God is referred to by believer as having a person relationship with God or being born again, which is completely non-understandable to unbelievers or even to the religious person that has not experienced God in a meaningful way. In view of this a person might be what we call religious and not have true faith. In this context faith is trust-based on one’s prior experiences.
My point is that if God does not show up as you might expect do not give up on God, rather take a look at your experiences and your interpretation of those experiences on which your faith is based.
 I had to add this expression for my atheists friend who make a big deal out of atheism be a non-believe and not a faith. Faith is simply trusting ones believes and I would hope that atheists have at least a little trust in what they believe in or what they do not believe in.
 The idea of the objectivity is somewhat of an inflated idea. Most human knowledge has some aspect of subjective-ism. This is the reason there is no end to questioning and doubting. It is the miserable lot of the skeptics to be doubting and arguing all the time and never coming to the knowledge of the truth.
