There is noticable increase in use of dark imagery in Eliezer's language as he starts to doubt his faith in god. When seeing burning bodies at Birkenau, he even asks himself "Why should I bless His name?" (44), showing his first doubts about the existence of god. Even though, Elizer began to doubt in god’s “absolute justice” (57), he whispers, “May His Name be blessed and magnified” (45). This shows that Eliezer still remains faithful.
Eliezer’s horrifying experiences during the Holocaust had shaken his own faith in god, which is shown in his own use of defying language. On the eve of Rosh Hashanah, when everybody in the camp had gathered together to celebrate, “In every fibre [he] had rebelled” (78) against the god and even asked himself “why should I bless Him?” (78) Eliezer had not only lost his faith and rebelled against god, but also accused god of choosing Jews “from among the races to be tortured day and night” (78). This accusation clearly denies the existence of the god itself, as Jews are taught by Talmud that as long as there is god everything will be taken care of, but the accusations clearly deny god as being good.
Despite asking hard questions about the existence of God, Eliezer does not abandon his faith in god. Even though, Eliezer had lost the faith in god and rebelled against him, “a prayer rose in [his] heart, to God in whom [he] no longer believed.” (103) when rabbi’s son had abandoned him during the long march. It seemed that Eliezer had completely lost his faith in god when he was accusing god of being responsible for holocaust, but when Eliezer prays for god to “give [him] strength never to do what Rabbi Eliahou’s son has done” (103) it is clear that Eliezer is slowly recovering his strong faith in god.
It is significant how Elizer’s faith in god differs in different parts of the book. Originally, when they all lived in peace and when they weren’t affected by the war in any way, Eliezer’s belief was unconditional, but as soon as harsh times start getting closer and eventually got there, a change in his faith becomes very obvious. First of all he just starts to have doubtful thoughts, but that soon changes into a denial of god’s existence. However, as times turns better he starts to get his faith in god back. The theme Faith in Night is not only used to show how habits change through different paths of life, but I think that it also emphasizes the holocaust and makes it even easier for the reader to imagine the tragedies that had happened to the Jews in the World War II.
