Then I said, ‘Ah, Lord God! I cannot speak, for I am a youth.’ But the Lord said to me, ‘Do not say, I am a youth. For you shall go to all to whom I send you, and whatever I command you, you shall speak. Do not be afraid of their faces, for I am with you to deliver you,’ says the Lord. (Jeremiah 1:6-8)
Short answer: Work at it.
Longer answer: Read, listen, attend, ask, study, change, improve.
I used to have a professional speaker in my church. When I asked her for advice, she declined. I was disappointed. I would loved to have had some helpful pointers from her. (Many years later, we are still in contact and to my pleasant surprise, she remembers only how effective I was. I’m thankful for her poor memory!)
I bought a magazine at Barnes & Noble the other day. OnPoint costs like a hardbound but is a slick quarterly from the Harvard Business Review. The entire Summer 2019 issue is devoted to “How to Become a Fearless Speaker.”
I paid $20 bucks for it.
If I get one or two great ideas, it’ll be an excellent investment.
And that’s another point worth remembering, pastor: Always be open to improving your technique.
