Deadly Enemy of Man [EPUB ebook] 

One of the earliest weapons of the devil against both spiritual and physical well-being of a man is enticement. The flesh attacks the soul through its poisonous activities. The flesh and its activities are very dangerous, but Christians have become so complacent that they sit back and allow these activities drag them off the track to heaven. You cannot afford to be gentle with the enemy because if you do not get him first, he will get you. The moment the enemy discovers your weakness, he will keep on hitting you at that particular spot.
