My friend Olan was invited to preach in a church. During his session, he called out two boys from the audience to serve as his sermon illustration.
He said, “Let say, for example, this is Joshua and this is Caleb.” To his surprise, every one in the audience broke out laughing.
Sympathizing with his puzzled look, one of the people explained, “You don’t know these boys, but you called them by their right names, that’s Joshua and that’s Caleb.”
