Are you one of these "I don't read books but the Bible" types?
Yes another question calculated to suggest I ignore the scholarship of the past. Exhaustive concordances, Bible dictionaries, Lexicons, Interlinear translations, and of course commentaries. Even in this thread I have referenced the work of others. So your question seems disingenuous, like something out of middle earth.
However, I do not claim to be a mind reader, and giving you the benefit of the doubt, I rely on many of the methods and practices I learned in discipleship class, such as inductive bible study. In the first step, "observation" we learned to look at the passage as given at the time. Thus we asked questions like, what was the culture, the historical setting, the meaning of idioms at that time, and what what was the mind-set of the audience given the revelation at that time. (Sounds alot like an abbreviated "biblical theology" methodology, although that name was not presented or used.) Some of the aids were bible dictionaries, and the new manners and customs of biblical times.
The next step was called "principlization" where we tried to discern what if any timeless principles were being conveyed in the passage. We asked questions like, was this being addressed only to the apostles, or did this apply to any of Christ's disciples. And if the principle was derived from the Old Testament, we asked whether the principle had been embraced or superseded in the New Testament.
Finally, the third step is "application" where we consider how to apply the principle to our lives, such as never do wrong to get a chance to do right.
