In putting some final touches on the letter to my mother (yes the one I've been preparing for about six months,) I came across this article from a 1984 Watchtower.
WHO does not want to avoid making mistakes? They can be quite embarrassing, often costly and so regrettable! Do we want to avoid distressing errors? Then we must guard against a trait that easily leads to them. We must beware of presumptuousness!
What is presumptuousness? It is "assuming a prerogative, privilege, or permission without warrant"; "overstepping due bounds"; "readiness to presume in conduct or thought." Indeed, presumptuousness makes a person proceed according to his own ideas and makes him resist counsel or correction.
But who are the presumptuous ones? Are they only the obviously wicked? Who really needs to beware of presumptuousness?
Foremost among mankind’s presumptuous ones are the persecutors of God’s people. They insist that they, rather than Jehovah, should be obeyed. Could any act of presumption exceed that?
That JWs (myself formerly included) cannot read this and perceive how it indicts the Watchtower Society itself is the sort of thing that makes me tremble in awe.
