An interesting scripture reminds us to be careful of those that question every good thing that the F&DS does:
Titus 1:10-16
"10 For there are many unruly men, profitless talkers, and deceivers of the mind, especially those men who adhere to the circumcision. 11 It is necessary to shut the mouths of these, as these very men keep on subverting entire households by teaching things they ought not for the sake of dishonest gain. 12 A certain one of them, their own prophet, said: “Cre'tans are always liars, injurious wild beasts, unemployed gluttons.”
13 This witness is true. For this very cause keep on reproving them with severity, that they may be healthy in the faith, 14 paying no attention to Jewish fables and commandments of men who turn themselves away from the truth. 15 All things are clean to clean [persons]. But to [persons] defiled and faithless nothing is clean, but both their minds and their consciences are defiled. 16 They publicly declare they know God, but they disown him by their works, because they are detestable and disobedient and not approved for good work of any sort."
That is why apostates need to be cut off from the congregations, because they are detestable and disobedient and not approved for good work of any sort. Jehovah sees it this way. Many are deceived by exjw and apostate websites. I do not want to be in their shoes when Jehovah comes knocking.
