Great to hear Elizabeth! you'll be fine. Don't over prepare - let the Spirit guide you - you'll have the words.
We have about 550 meetings a week here, but the type where someone leads for 15-20 min with a topic, and then everyone shares on it...maybe 3-4 of those out of the 550. We have either speaker meetings or closed discussion which is always out of the literature. So it's not a common thing here. I have spoken several times, and it's always a blast. Nervous, yup, but once you get speaking, it just comes to you.
Great to hear and thanks for sharing that
Paul
