Romans 10:17:

So then faith cometh by hearing, and hearing by the word of God.

Notes on Romans 10:17:

You already have the measure of faith (Romans 12:3), which gives you the ABILITY to believe.  However, you have no idea WHAT to believe until you hear the Word of God.  Then faith comes for specific blessings.

Some teachers have said that this verse should be punctuated to say that faith comes by “hearing and hearing” by the Word of God, meaning a continuous hearing.  I understand the point they’re trying to make – that you should keep hearing the Word rather than just saying, “I heard that already” without studying anything twice.  The original Greek is unpunctuated, which gives us liberty to repunctuate anything in a way that doesn’t cause a contradiction.  However, the “hearing and hearing” rewrite of this verse is incorrect from a Greek perspective because of the Greek word dia, which is translated by in this verse.  It usually does mean by or through.  So the rewrite would work without the word dia – “Faith cometh by hearing and hearing the Word of God” – but the presence of the word dia ruins that translation, as “hearing and hearing by the Word of God” does not make grammatical sense.  The verse is best left as-is.

You could cite plenty of other Scriptures about abiding in the Word; you don’t have to mispunctuate this verse to prove that you should keep hearing the Word.
