Why does Les want people to see what the book says instead of his own opinion?
He wants people to see what the book says because what man says or thinks does not amount to anything. He stresses that everything must be substantiated from Scripture, so the authority rests on the book itself rather than on personal ideas, opinions, or projections.
Les explains that once in a while he will present something as his own idea and say he is just projecting, but most of the time he wants people to see what the book says. His reason is that what man says or thinks doesn't amount to anything, and he insists that everything must be able to be substantiated from Scripture. He illustrates this by going to Acts chapter 7 when Exodus does not tell Moses's age, and by using Stephen's sermon as it reviews the Old Testament.
