Main thought: delve into the concept of God speaking.
Speech is communication by means of words and verbal expression. The nature of language, as I have argued before, is fuzzy and prone to subjectivism.
Written word vs. verbal word. Written lacks tone, appears more ‘objective’. It’s there, in black and white. Verbal has tone, which often changes the meaning of words. Consider:
‘Good job!’ (normal tone)
‘Good job!’ (sarcastic tone)
The exact same words, only slightly different tones of voice, change the meaning entirely – the meaning is reversed. Written words seem to bring context with them in a different, more static way – to use them in a context which they were not originally used in would be to rob them of their original meaning. Written word is frozen in its context, and can only have its original meaning if used in that context. Distortions of text, out-of-context readings, etc. Written text is not dialogic – one cannot ask the book questions it does not answer.
