life - faith = fear

the youth minister who i worked with always would say "fear is the lack of faith." and i am beginning more and more to really think that.
i am fearful of stupid things like elevators and spiders but can i actually be fearful to actually let myself like something? i think for years i have taught myself that failure or disappointment was just a part of everything and to just expect that as opposed to really shooting for the stars. so where does this lead me? to disregard something that i like, that i really think is for me. and what do i do? i do what i can to find a flaw, i search and strive to find some sort of detail that detracts me from it.
so is fear really the lack of faith? i think so. when you fear, it's something that is unknown and it's isolating. which is an elevator to me. you're in a box in the middle of a building with no windows, horrible lighting and no actual knowledge of whether the computer operating this several ton hollow box will open when it is supposed to. it's kind of like when i fear anything. i trap myself in this box and really only faith can open the doors to something new, you know? if i have faith that the doors will open, if i have faith that Jesus will provide everything that i need, then why have fear?
i think satan tries to isolate us in these boxes because when we are alone, we become vulnerable and begin to believe anything to get us out of where we are at.
at first i didn't believe what he would say, but now i can see the truth in it...
