When I served in the children’s ministry in my home church as a young adult, one of our faithful volunteers was Grandpa Ed. Grandpa Ed showed up nearly every week and was what we called a “listener”—he wasn’t in a classroom or teaching a Bible lesson, but as kids worked through their memory verses in their classroom, he was available in another area to work one-on-one with kids to memorize or recite their verse. And they loved him.
