Hello rocketman,
Thanks for your comment, and for your …question
“…never really say just how that happens. Is it by dreams? Visions?
… they never explain the mechanism that God supposedly uses to impart such "understanding"
I do agree with you …they avoid to give precise and definite answers.
From "The Watchtower " 1960 July 15 th , pages 438-9 paragraph 2:
“ Just as the early Christian congregation collectively
served as the channel of communication from heaven
to earth, so in our time.
(Eph. 3:10) Abundant spiritual
food and amazing details as to the doing of God's will have
been flowing through this unique channel actually as a
miraculous evidence
of the operation of holy spirit. "
From "The Watchtower " 1981 December 1 st , page 27
“Jehovah God has also provided his visible organization,
his "faithful and discreet slave," made up of spirit-anointed
ones
... Unless we are in touch with this channel of
communication that God is using,
we will not progress
along the road to life, no matter how much Bible reading we do."
From "The Watchtower" 2001 August 1 st , page 14, paragraph 8th
“Rather, he has complete confidence in the truth
as it is revealed by Jehovah God through his
Son, Jesus Christ, and “the faithful and discreet slave. "
As you can see, in these quotes the WTBS Inc. mentions:
“channel of communication “;
“revealed by Jehovah God”;
“flowing through this unique channel;
“miracolous evidence”;
“channel of communication from heaven to earth”.
So what is left out is the mode/instrument/mean
to transmit/send/give/impart the actual communication.
