All good suggestions, every one.
I never mark in Bibles because, for me, marking changes and tends to hide meanings the next time I read.
I use several study Bibles from when I was a Protestant and treasure the different strengths of each. The text of a study Bible is jammed with notes, markings, footnotes, cross references. Great for study. You may find different translations are better for some kinds of reading than others. Use several. Use all those Bible helps.
But I also like to do lectio divina (a slow contemplative reading -
defined) and for that I like to get the Bible text as plain as possible, even without verse numbers if possible.
You might like to read and keep a journal to write what strikes you as you read and pray about what is meaningful to you. It may seem odd, but writing may be an important part of your reading. It tends to make me understand and remember better. So, for how to read? -- consider a journal.
You also might like to read for:
1. Learning the historical context of a passage.
2. Seeing the allusions to OT parallels and Jewish customs and laws.
3. Understanding the shadings of the original Hebrew or Greek words and their distinctions from similar words.
4. Understanding the style of writing and manner of expressions and literary devices used in the drafting of the text.
5. Studying how a passage fits within the large theological themes of the Catechism.
6. Understanding the chronology of the passage in the overall chronology of the Bible. This helps me remember things.
7. Seeing how the passage speaks to topics that interest you -- prayer, seeking to improve some part of your life, helping with hurt and loss, finding courage, fighting sin.
8. Learning the ways of a fallen world.
9. Learning about spiritual gifts.
10. Enjoying the beauty of God expressed in his Word.
11. Growing closer in love to God, Jesus, and the Holy Spirit.
You might enjoy reading the Bible while you listen to the same translation on CD or MP3. For some reason, doing this outdoors is the way I like it the best.
If you can read the Bible in an old church -- another way to read -- different from all the other ways -- seems to me. There is something about the stillness in an old church -- affects the reading and the seeing.
Main point: You are already on the right track and headed in the right direction -- follow the lead of your praying heart -- God himself will be your best guide in how to read his word.
Blessings to you.
