I am starting to feel such a calling - like perhaps the call to a pastorate was, for this time, like Abraham's call to sacrifice Isaac - after all, it would be utter foolishness to leave with the economy the way it is, and with me owning my home, no mortgage, etc.. However, I understand that God's plans dont' always make sense in man's timing, and I was faithful to God's leading, and feel that He has blessed me through it. He wanted to see how willing I was to follow Him all the way.
Now, what I'm doing...well, obviously, be sure of your salvation and that you're walking with the Lord, as was said.
Then, even before, when I was sending a few resumes about serving as a pastor, I was telling churches I'd be available to come speak missions, family, or whatever conferences. that helps to get my name out. I have also planned to get my name around at ministry conferences like one I'm going to in a few weeks.
I am also studying Scripture at various points, and have felt that the Lord may be leading me to write. I tried before, but my topic was so broad that I had trouble focusing. Now, I am focusing on 2 Kings 4 and the story of the Shunnamite (sp?) woman, and how someone from a broken home can dedicate themselves to Christ and become a Christ-honoring witness and leader even with no male role model. Sometimes we forget those homes where people aren't fortunate enough to have a male role model, or at least not a saved male role model. The story in 2 Kings in a great example of a woman (the KJV calls her a "great woman") who overcame the obstacle of a husband who was there physicall but not spiritually.
Even if God doesn't call you to write books, has he called you to write articles? I don't know how those in the Baptist Bible Tribune and others do it, but that might be another way to get name recognition.
I only mention writing because...well, part of it is I like doing it myself, but also, it can be a good way to get your name connected with a certain type of interest (family, missions, youth, etc.) However, even if you don't write anything, there are plenty of avenues to getting your name out. I am not sure how you get your name on the Baptist Bible Fellowship list, maybe you have to be a BBF graduate, but at www.bbfi.org
they have list of spekers.
I would recommend only taking up love offerings, or asking that transportation be paid for if you have to; we just had David Ring at our church recently, and that's all he did. And, I wouldn't have minded if our church paid him; he was awesome!
Be friendly with everyone, be willing to let the Lord guide you, build relationships, because you are not only dealing with brothers and sisters in Christm, you are dealing with people who will spread the wrod.
