In 1979, the adult Sunday School class of a Baptist church, phoned the Auburn Alabama Branch of The Church of Jesus Christ of Latter-day Saints, asked us to send someone to explain our Church to them. I was 23, and they sent me.
I made this presentation with posterboards, putting them up one by one. They loved it.
In 2022, I recreated it as a Google Slides presentation. I sent the link to about a dozen of my friends, and suddenly, I had six families taking the missionary lessons.
Perhaps you and your friends could benefit from it also.
