My grandfather [George A. Smith] used to say to his family, There is a line of demarkation, well defined, between the Lord’s territory and the devil’s. If you will stay on the Lord’s side of the line you will be under his influence and will have no desire to do wrong; but if you cross to the devil’s side of the line one inch, you are in the tempter’s power, and if he is successful, you will not be able to think or even reason properly, because you will have lost the Spirit of the Lord.’
