I am trying to remember a verse I've heard, and almost positive I've read, before.
I do not remember the exact phrasing.
It was similar to: 'If no one is there to witness, even the rocks of the field and [trees? mountains? nature?] will witness/speak the word`. I believe this is in the New Testament, possibly Jesus speaking.
What is the passage that relates to what would happen if no one was around to witness?
