My pastor’s sermon notes are on his laptop and some people in the congregation use tablets to pull up verse readings.
Pales in comparison to the future shock of a church in Florida 4 decades ago that installed drive-in movie speakers so people could sit in their cars and listen to the sermon when the church was filled to capacity.
In Seattle, where my daughter attends, one can text questions to the speaker during the evening Bible Study. He is on a stage and there is a good sized audience.
