By laypeople, we mean non-preachers.
Speaking in church refers to addressing large groups of the Lord’s people.
Many non-preacher types are outstanding on their feet in front of large groups. Schoolteachers come to mind. They are experienced and at ease. But the typical church member, even one who teaches a Sunday School class, may feel out of his element when asked to deliver a talk in front of the congregation.
Marlene said to me, “I’m sorry I took the entire service, Pastor. But the Lord was leading me.” Translation: She was unprepared, really got into her talk and couldn’t control it. As a young pastor, I was inviting church members to share testimonies in the morning worship service, something along the lines of 5-7 minutes. (Later, I learned to interview the individual and keep hold of the microphone the entire time!)
Once Marlene got going, she could not find a convenient stopping place. She kept on for a full 40 minutes. (I could have pointed out a half-dozen great places to stop!)
Now personally, I would not blame my failure to prepare for a speech on the Lord.
I see it happen all the time. It can be almost embarrassing.
