I can see how Bible aps can be very convenient, but there is still something special about a book that just isn’t the same using a device or Kindle.
The Bible isn't about paper, print, and binding.
It is about the Word, however that Word can be received.
In Jesus's day, Scripture was read to people in synagogue. The same thing is true until the printing press was invented (frankly, not too long ago in the scheme of things).
Anything that can be used to get people to hear the Word is absolutely wonderful and sacred!
Yup
One can write other references on paper.
