What lessons does the narrator seem to learn from Moshe's experiences in telling his own story?

When Moshe the Beadle is asked why he prays, he replies, “I pray to the God within me that He will give me the strength to ask Him the right questions.” In other words, questioning is fundamental to the idea of faith in God. The Holocaust forces Eliezer to ask horrible questions about the nature of good and evil and about whether God exists. But the very fact that he asks these questions reflects his commitment to God.

Discussing his own experience, Wiesel once wrote, “My anger rises up within faith and not outside it.” Eliezer’s struggle reflects such a sentiment. Only in the lowest moments of his faith does he turn his back on God. Indeed, even when Eliezer says that he has given up on God completely, Wiesel’s constant use of religious metaphors undercuts what Eliezer says he believes. Eliezer even refers to biblical passages when he denies his faith. When he fears that he might abandon his father, he prays to God, and, after his father’s death, he expresses regret that there was no religious memorial. At the end of the book, even though he has been forever changed by his Holocaust experience, Eliezer emerges with his faith intact.
