Why does Les Feldick put Scripture on the board during his teaching?
Scripture is put on the board so viewers can see exactly what the Book says, not merely what the teacher says. It responds to requests and helps the television audience follow along in the Scriptures, emphasizing what the biblical text itself says.
Les explains that a visiting missionary was impressed that the class had their Bibles in front of them and were taking notes. He notes that most of the television audience seems to follow along in the Scriptures too. Because of viewer requests, they began putting Scripture on the board so people could actually see what the Book says—not what he says, but what the Book says.
