"He is one of his scouts. He goes about to see how the land lies, and where he sees a favourable opportunity of Depression getting an entrance, he prepares the way for him. In fact, he is in his pay. Did you not notice how Depression had the poor wounded man in his grip? If ever he sees a man worsted in the fight, he at once joins company with him. I do not know what other enemy had wounded the man we passed, but I know that Depression was standing over him with his poisoned arrows, hoping to kill him." "Then I must have nothing to do with him," said Iddo, "and I must pray for Amer instead of dreaming about him so much. I shall grow happy praying for him." And Amer needed the prayers of his little friend and of her mother, for his path now led him through a very dangerous part of his journey; and what made it all the more so for him was the fact, that for the greater part of the way, some of the words of the preacher to the crowd, to whom he had listened, filled his mind. Amer did not know that the enemy Doubt was walking invisible by his side, suggesting difficulties in the Guide Book, neither did he know that the decision to talk over some of these difficulties with the people he met was also the work of the enemy. Being of a somewhat speculative turn of mind the matters brought forward by the preacher had interested Amer greatly, and he did not realize that to throw scorn on one part of the Guide Book was to weaken the whole, and to take away much of its helpfulness as a guide. Neither did he know that the Guide Book and sword were so connected that to doubt the one was as good as throwing away the other. He forgot the advice of the Ambassador to cling to his Guide Book, and his warning that to lose it was to lose the battle, and so to lose his soul. Had he followed the same course as Heman, instead of listening to the opinions of men like himself and to the whispers of the enemy, he would have met him in open warfare, crying to his King all the time for help. Afterwards, when he looked back upon this sad part of his journey, he remembered how little at this time he was really using the Book as his guide, or studying it as he did at first. His mind was full of speculative questions, and while this was the case he did not study the Book to learn from it truths which would have helped on his spiritual advancement, and have made him strong in case of attack. His path led him across the land of Achshaph.* It was a land full of danger to the unwary, but thousands of pilgrims had passed through it unscathed, because their armour was bright and their sword in their hand. For those who asked for it, a special guard was sent to take them across; an invisible guard, but a guard that never failed to bring them in safety to the other side; but Amer, instead of a guard, had for his invisible companion the enemy Doubt, and so drew near to the land without fear or much thought.
