Underscoring a Book Passage
Driving home: And if these words, underscoring the necessity of the new birth, are to be changed, then Jesus Christ in person must be changed. And this is impossible.
Martin uses the analogy of underscoring a passage in a book to emphasize that Jesus's 'Verily, verily' statements are His own divine emphasis, not making His words more true, but highlighting their unchangeable importance.
The verilies of the Bible are like God Himself taking a red pencil to underscore His own word. Now it doesn't make it any more His own word. It's His word whether you underscore it or not. You're reading a book, and you come across a passage you want to remember.
