He speaks of the backsliding process. About the process to giving in to temptation. About the allure and appeal of that which is just out of our reach. He likens delusion to being under the influence of laughing gas in a dentist chair. How that a backslider is under such influence, and periodically there are times that they "come to themselves". A moment of clarity when the fog is lifted for a moment. When the "influence" is lifted for a moment. And how critical it is to take advantage of that moment, to respond correctly to God.
