the evident demonstrations are based on facts. An example that you may understand might be when a marriage proposal takes place. If that proposal is backed up with an engagement ring, then an 'evident deomonstration' has taken place. Though the marriage has not taken place yet, each are assured of the 'future reality' that they will be married.
No they are not "assured" and this is precisely what I am getting at... If you and your partner get engaged there is a chance that the engagement might not be fulfilled into marrigage, correct? Lots of engagements don't work for various reasons.
However, in order to for you to not feel uncomfortable (i.e feel a cognitive dissonance) you must assure yourself (and perhaps even lie to yourself) to give you confidence that you have made the correct decision.
e.g:
"Oh I hope he/she really loves me"
"I hope she/he doesn't go back to his ex-girlfirend/boyfriend"
There is no material or logical evidence to assume that the above wont happen, you must "have faith" or reassure yourself that you have made the right decision based on no evidence.
Now apply the same line of thought to the bible and it's claims of supernatural happenings...
