Why doesn't a Bible teacher have to tell people to stop doing specific things?
A Bible teacher doesn't have to list specific behaviors to stop because faith in what the Book says reveals sin and guides the daily walk. When people get into the Book and believe what God says about certain activities, they recognize sin themselves and take appropriate action.
Les explains that people have told him they appreciate that he doesn't condemn this or that. He says he doesn't have to, because he doesn't have to tell people to stop doing this and stop doing that. The reason is faith. Faith is the one-word key for recognizing sin and dealing with sin. Unless a person can believe what God says about certain activities or acts, they don't know it is sin; but when God says it and they believe it, then they know what it is. The whole daily walk is prompted by faith in God. He connects this with Romans 3:23, where all have sinned and come short of the glory of God, and says the first step in salvation is to believe that I am what the book says I am. Faith guides not only into salvation but all through the Christian experience, based on what the book says, not what someone else says. So as soon as people get into the book and see what it says by faith, they will take appropriate action.
