This can be a very interesting part of the note making, as you look back on what you once thought or understood about certain texts -- both where you have changed and where you have remained the same (or maybe even strengthened a view).This is my old Ryrie Study Bible from my Bible College day in the 80s. I stopped using it in the 90s. When I go back and read all the notes (most of which I dated), I can see how my understanding changed over the years.
