I don't quite get the "all embracing" part. At best, I gather that here we are only considering absolute faith, nothing less, even though weaker faith is also common.<quoted text> Faith is not limited to religion alone, it is all embracing.
It is a belief in something not yet seen, like the discovery of hidden treasures and the likes. Faith goes with unstoppable determination.
OK, yes, mostly it has to do with expectation, I agree. For instance, if my light switch worked the last hundred times, I would have faith (confident expectation) that it would work one more time. That would be an example of belief in something not yet seen.(Doesn't matter that I saw it work before, I haven't seen the next attempt yet.)
Although I can think of a case where it is not a matter of expectation:
"I have faith that the sun rose at the correct time yesterday morning."
or "I have faith that Joshua's army killed every man, woman and child in Jericho except the relatives of the prostitutes." The first case perhaps being informed by my general faith in the science of the motions of the solar system, and the second case perhaps due to my trust in authority. Although perhaps it is still a matter of expectation, the one that I will not be disabused of that faith by evidence that might come to my attention later.
I can understand the association with determination, but not that determination, no matter how strongly motivated, is always unstoppable. That's only a romantic view of great determination. Such is another issue however.
