I have written more under my page, Baha’i – My Belief, and link to ‘What is Faith?”. My short argument is that faith is an inherent aspect of the human mind / brain function. Connected to the ability of humans to ponder on the future and recognise the possible inconsistencies in the provision of needs, faith develops on a functional structure of the brain that allows us to deduce there is a consistency in life that we can rely on. On the other hand there are many unknowns. Faith, then provides us a capacity to behave in accord to a judgement about the unknown that we can then rely. As a definition, I have come to a conclusion that Faith is a sense of security with the unknown as deducted by a belief in the consistancy of provision of resolutions to need.
