“Accursed is one who leads a blind person astray.”
~ Deuteronomy 28:18
One of the consequences for the really bad transgressions is being cursed.
But what’s so terrible about misleading the blind? No one gets killed!
When someone who sees less than you – whether literally or figuratively – allows you to direct them, they’re putting their lives in your hands. If you deceive them, you break more than just their trust in you, but their ability to trust anyone.
Conversely, if you affirm their trust in you, you strengthen their faith in everyone.
