How does the author show a central idea of losing faith in Chapter 3 of Night?

In Chapter Three, Eliezer watches in horror as a truck full of children drives up to a giant, fiery ditch and the children are put into the flames. Eliezer's father is sad that he is going to see his only son consumed by fire, and he tells Eliezer that humanity is not present in the concentration camps. As the parade of men starts to recite the prayer for the dead for themselves and his father begins to weep, for the first time Eliezer feels himself revolt against God. The men march closer and closer to a fiery ditch, but at the last minute, they swerve away from the fiery ditch. Eliezer says he will never forget that night and the children's faces that he saw burned in flames. On that night his faith was consumed, and the silence of the night made him lose his will to live.
