Aspirations and ability are two different things

I have relistened to the tape of my sermon tonight. Just about 15 minutes worth. Maybe less than that. I tend to have had a bunch of “and umm…”‘s in it.
I really have thought about being a part time preacher. Maybe just preaching at rural congregations on occasion. I admire excellent preachers who are able to spread the word effectively. I may never become one of them. I have gotten past my nervousness and apprehension when speaking in front of people. However listening to the tape just makes me wonder if this is even cut out for me. Aspirations and ability are two different things.
