Indeed we live by faith, and things are constantly changing, even as we speak, and yes we do have control over some things, than others, and that is what this life is all about constant changes, and daily challenges. Therefore, people are in the position to change what the truth is for them as often as they feel necessary!

There is a saying that nothing is written in stone, and what was written in the past, may not be the same truth today!

we react on many occasions, unfortunately, to our unconscious program for responding to the input of sensoy perception.
so, is it 'faith' then unsimilar to what some may call 'intuitition', when they choosing not to really think about the situation, rather just react to or on it at the most popular 'faith' level or that level of your dogmatic following.
is it then necessary to believe in that which can only be measured/quantified, or
may the symbolsim of the story of 'doubhting thomas' be pertinent here?

Faith is the gap between what you know today, and what you will accomplish tomorrow.

If I start a business, I have to have faith that it will succeed. Without faith, I would have to learn everything there is to know about running a business, so as to remove all uncertainty about succeeding. The problem is, it's impossible to gather enough information to remove all uncertainty.

While it is undoubtedly essential to have good information, it is more important to be confident in your ability to learn whatever you need to learn to succeed, and to have the inspiration to persevere in spite of difficulties.

That's what faith is.

We don't allways know whats in store for us,we tend to create a life of our own accord.Its faith when you apply it to seeing an end resolt.We try to keep our faith as life goes on,but as humans we try to get it as fast as we can.Wich in a way we rely on ourselves instead of the Devine Light.We all must carry the faith at all times,its why we exsist.Until you've been openened up to the truth of life and whats all out there,you really go by blind faith,instead of knowing.Even when you know it,it still rely's on faith,not only to your higher power,but its becomes more into yourself.We all have the power to hear the answers to life,but without Faith we can't fully understand them.There is a bueatiful Afterlife and its waiting there for us.Look at life as a open book,it will allways give you a good story,and if you let it,it will be a happy ending.
