You can lose faith in the world, you can lose faith in your friends, you can lose faith in God, you can lose faith in yourself. It is dangerous to lose such a thing as faith, because faith is all we have.
faith: 1. complete trust or confidence. 2. strong belief in a religion. 3. a system of religious belief. origin Latin fides. [Oxford Dictionary of Current English, paperback, 2001]
There you have it. A dictionary definition of faith. And in that definition lies the fault and the faculty of that word.
'Complete trust or confidence' meaning that your dedication to the subject is unbroken, unyielding, a perfect circle, and in there being, an impossibility, and an improbability. An ideal that exist in theory but not in practice.
Have faith that things will work some of the time and not all of the time and you will be adjusted to the workings of this world.
There will be irregularities in everything there is, so that it can fit in this puzzle of life. Any idea that states absolutes as whole and complete truths are not only obnoxious, but ignorant and inconsiderate.
Have faith that things will work some of the time and when they do not, have faith that you will be strong enough to bear the loss and have the reserve within you to recover from it.
Then you will be whole, complete and well adjusted.
