These are the Scriptures that testify about me, yet you refuse to come to me to have life. Be willing to have your old opinions and assumptions challenged, and to be shown sins that you need to repent and be forgiven of. Be ready to obey. Keep your expectations realistic, both for the books you're buying and for yourself. Serious Bible study is work.
People often like the idea of doing Bible study better than the actual work.
There are no magic books that will give you all the answers without effort on your part. On the other hand, don't underestimate yourself. The spirit in which we approach the Bible and read and study it is far more important than our ability to use even the most sophisticated Bible study tools.
