Why they are terrified of JWs visiting apostate sites:
"The first to state his case [[Watchtower]] seems right, Until the other party [[the apostate]] comes and cross-examines him." - Proverbs 18:17
Their prolific publishing and studying of Watchtower literature is not healthy according to Ecclesiastes 12:12:
"... To the making of many books there is no end, and much devotion to them is wearisome to the flesh." - Ecclesiastes 12:12
Their haughty attitude of comparing themselves to other religions so as to exalt themselves as the truth and condemn the others as nothing, is condemned by Jesus at Luke 18:9-14.
They love to misuse Proverbs 4:18 to justify their prolific history of changing errors but 2 Timothy 3:7 is more pertinent:
"always learning and yet never able to come to an accurate knowledge of truth." - 2 Timothy 3:7
The gullible willingness of JWs to accept any and every changed teaching promulgated by Watchtower:
"... children, tossed about as by waves and carried here and there by every wind of teaching by means of the trickery of men, by means of cunning in deceptive schemes." - Ephesians 4:14
They love to cite Matthew 23:9 to condemn Christendom's use of the title "Father", but are hypocritically blind to how their having a group of brothers called a "Governing Body" violates the spirit of Jesus' words in the very next verse:
"Neither be called leaders, for your Leader is one, the Christ." - Matthew 23:10
99.9+% of JWs reject the heavenly hope and they discourage persons they study with, from having the heavenly hope:
“Woe to you, scribes and Pharisees, hypocrites! because you shut up the Kingdom of the heavens before men; for you yourselves do not go in, neither do you permit those on their way in to go in." - Matthew 23:13
And I'm only just getting started ... don't get me started ...
