I do but I use dry highlighters and pencil only. Why not pens? Because in my first marked up Bible I wrote in it with the same pen that I was taking notes with, when God cleared my vision enough that I understood some passages I couldn't erase my backwards thinking about God. Now that I am far enough away from that mindset I can look back on how far God has brought me, however, there are some thought patterns that I never want to think through again.
