JWs claim to be fulfilling Mathew 24:14...
But JWS are just preaching false prophecies and doctrines created by the leaders of the Watchtower Corporation, who scripturaly are sinning apostates (false prophets) ?
They made a personal vow at baptism to be obedient and subservient to those men.
People who say things against Jesus's instructions for preaching his Kingdom Gospel are sinning apostates.
Of course one has to to read carefully the words of Jesus to understand that, which the JWS are demeaned to do, that is actually read the bible without the WTS's own interpretation.
