In over my head?

I'm not a quitter. When I say I'm going to do something - generally I do it. (Unless its the gym - yeah that lasted like 3 days). Tonight I started a 2 year bible/leadership course at my church. I'm pretty excited. I was pretty excited. Well, I'm still pretty excited, its just that - I don't know what I'm doing there. I'm not planning on being in any form of leadership any time soon. Some of the people in the class have been in ministry, are currently in ministry....want to be in ministry. I guess we're all called to be ministers, but..... Why did I sign up? Thats what I said! No really, I had heard about it a while ago and thought, Wow, that is something I'd like to do. This summer I decided I would try to go back to college and that I wouldn't have time for this course. Well, school fell through and I felt like God said, "Now you have the time. I want you to do this." I sure hope that was him and that I'm not doing this to fulfill some selfish desire to complete this course just to complete it.....anyway. Well, the first thought I had as we're sort of going through the introductions is that, Man, I am SO out of place. I wanted to quit. Sorry, I've made a mistake - have a good year. SEE YA SUCKA'S!!! I won't do that, but its what I was thinking. Anyway - I'm still excited about it. I am pretty sure everyone in the class is married....and I'm single. Thats ok. I don't care. (I probably wouldn't have metioned it if I REALLY didn't care, huh?) I'm not going to quit. I quit the gym, thats enough for this month.
