Belief means faith & life based on faith. Any anything you faith on, you'll receive answers from it & will make things happen by it.
The willful rejection of reason, or; an adoption of uncertain claims in the absence of factual support.
"Faith is still believing after a century of futility that the Cubs will win the world series." -- Ralph Bradshaw
Belief is the personal acceptance of information one holds to be true. It is based off of fact and/or faith.
Here is the literal -
Belief:
1. An acceptance that a statement is true or that something exists.
"his belief in the value of hard work"
•something one accepts as true or real; a firmly held opinion or conviction.
"contrary to popular belief, Aramaic is a living language"
•a religious conviction.
"Christian beliefs"
•2. Trust, faith, or confidence in someone or something.
"a belief in democratic politics"
My Personal preference is number 1 with this added - "1. An acceptance that a statement is true or that something exists based on natural observation and scientific theory."
I believe I'll have the roast beef on rye.
See? It doesn't mean I'm absolutely guaranteed to eat a roast beef on rye. Much could go wrong. The place could suddenly catch on fire and be evacuated before I can even make it through the queue to the cashier. They could be out of roast beef. I could receive a distressing text and have to leave, even after I'd gotten the sandwich but before I'd taken a bite.
Belief takes place in the brain. As does all the rest of human experience.
