A theme that the author develops through these 2 excerpts is that , despite how good u are doing if u are disobedient, u will find yourself in a bad situation
The author develops the theme of disobedience in both excerpts. In the first one, the author develops the theme by describing how Lucifer "fell through sin." The fact that Lucifer did not respect the laws of Gods caused him to be condemned to Hell.
In the second passage, the author develops this theme by explaining that Adam disobeyed God by eating from the forbidden tree. In the same way Lucifer was sent to Hell, Adam was similarly placed in Hell.
Ok this is probably late since I just got this as a district writing FSA sample thing but you can write about peer pressure, mental health (specifically depression) and how rewards impact decision making. :)
