Stating the obvious, we don’t see blind spots. That’s why they’re called blind spots. So, rather than being defensive when someone points something out, let’s listen to advice and accept instruction – – that in the end we can be wise (Proverbs 19:20).
Proverbs 17:10 – A rebuke goes deeper into a man of understanding than a hundred blows into a fool. That is, a man of understanding doesn’t defensively deny blind spots when they come his way. He allows them to shape his character.
