When we married, I asked him for a new Bible for my birthday. He came through (of course), and I resolved not to write in/highlight/underline in this one.
I like my old Bible with all its underlining and notes, but I really wanted to allow the words to speak to me freshly each time I read them. The previous markups remind me only of the previous lessons from those particular words.
So, what do you do? Do you mark up your Bibles, or do you leave the pages as they are? AND why?
