Xanthippe,
I mentioned at the outset of this thread that there is a "Linchpin" effect to the Bible that needs to be observed, in order to completely understand it.
I asserted in the first post that without this "linchpin," one cannot properly understand the Bible in its entirety.
I also decided to use John 16:13,14 to show Jesus explaining the future role of the coming "Spirit of Truth" in the final days, which with God's help would ultimately lead mankind into "ALL TRUTH" and declare the future for their benefit. In this way, Jesus taught us the "Spirit of Truth" becomes a secondary "messiah" or special "teacher" [a "Linchpin" to understanding the bible] for our day and time, sent by Jehovah God and Jesus Christ ... authorized by them. (See John 14:26; John 15:26.)
Luke 17:30 tells us this modern-day Messiah would need to be "revealed" as it were, for mankind's benefit at the advent of his role as "Spirit of Truth."
So, instead of anyone "joining a club," or something ... all one needs to do is to get his bible out, meditate on the verses in it, and put on his "thinking cap."
