Arthur my friend, I have never preached a day in my life. I have no idea what is happening to me. I am called. Seriously. It's nuts. I am half hoping that it will go away. I am just walking down a path and seeing where it takes me. And: I am walking slowly. But it feels right.
I went through exactly this, 9 years ago.
Don't mean to scare you, but I've since given up my job, my home, my previous life, moved 2000 miles away from my family to attend seminary, spent 3 years as a hospital chaplain (including 4 units of CPE in a residency), and have had my ecclesiastical council held.
I interviewed last week with a congregation on the east coast searching for a pastor; I'm hoping that we're mutually agreed that I'm the pastor they've been seeking.
