I believe that the sun will rise tomorrow, is that a true belief?
What's the difference between a belief and an expectation.
I believe and expect the sun to rise, because it has been doing this on a regular schedule, just like old faithful.
To believe Jesus will return soon, based on a 200o year old book, interpreted and translated by man is different.
Both are predictions. I think the probability can be reasonably expressed.
You can use your own technique to determine your expectations.
