Faith in fear

The problem with faith, faith is terribly hard to discern from fear, I for example, have always been one to say that I have faith in God, (not really so much in religion, just God), now here is the thing, I do a lot of things (or don't do them) because I am afraid of the consequences of doing otherwise. Fear is a useful tool but not really a good motivator. is it really any wonder that I have always had trouble with faith? Whatever is the truth I'm sure that it will make it's self known through some way unforseen, in a timescale that I don't have enough patience for, and when least convenient of course, as usual.
