The image is from Grant Horner’s Bible and it leads to a pleasant challenge for all of us.
How about writing in your Bible (and other places like journals) to leave a wonderful gift to your children, their children, and who knows whoever else!
Personally, I mark up four Bibles: two in English and two in Greek. We have two sons so each will have somewhat of an idea of the things which struck me most. I try to keep my penmanship fairly neat, but even when it is unclear what better gift could you give someone from your family?
My wife, Doreen, has a heavily marked up Bible, but because of smudges from the wrong kinds of writing instruments, some of the notes will only be known in eternity!
I was glad to see this post last year:
