There is an interesting reality shown in the Book of Mormon.
When Amalakiah flees to the Lamanites, he convinces the king of the Lamanites to go to war against the Nephites. The King of the Lamanites declares war and is met with incredible resistence. A large number of people actually organize against the King's declaration and gather at the top of a mountain in preparation to weather the King's wrath and armies rather than go to war against the Nephites.
How did Amalakiah transform the Lamanites so quickly? They are at war with the Nephites within a year or so.
Alma 48:1 And now it came to pass that, as soon as Amalakiah had obtained the kingdom he began to inspire the hearts of the Lamanites against the people of Nephi; yea he did appoint men to speak unto the Lamanites from their towers, against the Nephites.
2 And thus he did inspire their hearts against the Nephites, ...
3 ... for he had hardened the hearts of the Lamanites and blinded their minds, and stirrred them up to anger, insomuch that he had gathered together a numerous host to go to battle against the Nephites.
So the question becomes, for our day, what falsehoods are being taught to us from from the towers?
Are we listening?
Are we giving the preachers on the towers time and advocacy within the walls of our own home? Do we let our children sit to listen to these teachings on television, music, movies, or on the internet? Do we believe they are immune?
