How many times have you heard a JW say something along the lines of "This must be God's organization because of [INSERT REASON HERE]". Most of those reasons could equally apply to almost any organization on earth, including secular businesses.
The most recent one I heard was from an elder trying to convince someone why the Watchtower is God's organization. His reason was because "It [the Watchtower] wouldn't have lasted this long without God's backing". That same reason could be used on the Catholic church, IBM ... etc. I heard this same line of reasoning at an assembly. The story was the Watchtower got an unbelievable deal on printing presses. Another example from the podium was because of the love between brothers.
Have you heard this type of reasoning being used?
