In answer to your question, I would say that you must distinguish between what questions you want the text to answer and the questions that the text wants you to answer. I still contend that you should keep your inductive bible studies in the smaller of the books. When you approach the Old Testament books, you are going to be dealing with segments that are bigger than you are used to examining. Whereas in Matthew, you might determine a segment to be one and a half chapters, when you come to Isaiah – a four chapter segment is tiny, think more along the lines of ten chapters.
So then if you are going to begin looking at Genesis, you want to determine segments. Once you determine the segment breaks and corroborate them through terms, structure, etc. you should be able to see similarity in the content and direction each segment emphasizes. You may also find that Genesis bears a striking resemblance to epistolary or ideological material, in that an idea is presented in the first segment and the following segments build off that concept. You may not find that is the case, but if you do you must validate that through the tools of inductive study. The key is figuring that part out during your second phase of Inductive Bible Study, which is of course the ‘Asking Questions’ phase. During this part you must determine whether or not the questions you are asking are contextual or not. For Instance, where your interest is concerned, any question about the fall of Lucifer in Genesis 1 is not contextual. The chapter says nothing about a gap of time between verse one and two. Not that any of that stuff is wrong, it’s just not there in Genesis 1, therefore neither Lucifer or the gap theory have anything to do with what the author of Genesis wanted to point out in the 1st chapter. The most frequent repetition in that chapter is an indicator as to where your questions should be focused. Distinguish between what questions you want the text to answer and the questions that the text wants you to answer.
