Do you know your potential?

I saw a movie today - the first in a while - that has me thinking. It was "Lady in the Water" by M. Night Shamylan and I really liked it. It's different than his previous movies - a lot more humor, almost poking fun at himself at times, and based on a bedtime story. Of course, his movies always have some bigger, "universal" themes to them, and this one dealt with people understanding who they are and living up to their potential. If you haven't seen it, I don't want to give anything away, but there are several characters who are challenged by things that they are asked to do, or we in the church might say, are "called" to do. The main character in particular doesn't see himself as much of anything but gets called upon to do great things that he think he is unable or unfit to perform. Likewise, the female lead doesn't believe she is able or brave enough to fulfill her role - she says that the others make fun of her because she's usually clumsy. I wonder how many of us feel that same way...

When I made the decision to come to seminary, it wasn't so much about the job I would be doing when I was done but about the experience of studying theology itself. I love seminary - the learning and conversations that wouldn't happen anywhere else. I thrive on it, but I have no idea what comes next. Am I being called to something great? Who knows?! Right now I'm just trying to complete classes and graduate in May, but there has to be something next. I need to find a job to be commissioned as a Deaconess in April, but I don't even know what kind of job I want. I keep saying that I don't want to preach, that I'm not meant to be a pastor, and the truth is I think I'd be horrible at being a pastor. I don't have enough patience or interest in the business side of things (to begin the list). However, I also have to admit that I'm terrified of preaching. I've never done it before, and my adamant denials that I'll preach probably come as much out of fear of success as they do from lack of experience. I don't want to be a good preacher - and yet it's not my choice. I'm in preaching class this semester, so we'll see what happens with it. I don't know if it means anything, whether I'm good or bad at it...
So what are you afraid of? What do you think you could have been had you not held yourself back? Do you think you are called to something beyond what you are now?
