After you have spent time with God in prayer, asking God which scriptures that He wants you to study, read a portion of scripture. It could be a few verses, a whole chapter or even more. As you read try to observe the context of the text.
Note, as you study scripture, it is a good idea to study it in consecutive order. That is, if you studied John chapter one today, the next time that you study, you should begin with John chapter two. If you jump from here to there, you will probably not learn very much.
