What is an example of Christian falling away from the journey?

“So Christian turned out of his way, to go to Mr. Legality’s house for help: But behold, when he was got now hard by the Hill, it seemed so high, and also that side of it that was next the Wayside, did hang so much over, that Christian was afraid to venture further, lest the Hill should fall on his head; wherefore there he stood still, and he wot not what to do. Also his Burden now seemed heavier to him than while he was in his way”

The Narrator, p. 25-26

This is from the section when Christian has followed Mr. Worldly Wiseman's advice and strayed from his prescribed path to the Wicket Gate. As he is going down this alternate path to Mr. Legality's house in the town of Morality, he finds that his journey has more difficult and his burden much heavier than it had been on the Evangelist's recommended route. Hawkes notes that the increase in the weight of Christian's burden indicates Bunyan's opinion that "the purpose of the law is to increase our sense of sin" (25). This increase seems rather unnecessary, as Bunyan believed that justification was by faith alone, and not by one's good works. Thus, not only has Christian strayed from the path set for him by the Gospel (via the Evangelist), the detour has increased his sense of sin. Readers should note that Christian's true path is not free from a sense of sin, at least at first, and Christian is still weighed down by a sizable burden (his sin) even after getting back on the right path. His burden doesn't fall off until he has a vision of the Cross, at which point a Shining One comes and gives him the certificate of election (45).
