Feeling blindsided

I joke a lot about the fact that I don't have much peripheral vision in my left eye. Because of this, I sometimes bump into walls (or sometimes people) and some times it hurts a little. But I was really blindsided today and it has nothing to do with my eyesight. Our head pastor who has been with us for five years and who I like very much told the Session last night and the entire congregation, via e-mail today, that he has accepted a position in a church north of Chicago and will be leaving us in January. While intellectually I understand his reasons - a move up the career ladder, closer to his and his wife's families and more - I still deep down am feeling bereft. How can he do this to us? I know I'll get over it and we will probably call an excellent new pastor but right now I am not at all happy about this. Not very Christian of me I know but there it is. OK, I've vented now and I already feel a little better.
