Faith is your imagination to believe in something you can’t yet see and don’t know how it’s going to happen.
Fear is using your imagination to believe something you can’t see yet will not happen because you do not know how it can.
You’re not being asked to figure out the HOW. You’re being asked to imagine already having it now.
Doubt is imagining that you can’t have it.
Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.
Mark 11:24
