Uncantone, help me out on this one. What do you mean? Not being rhetorical. Kindly state your argument.
When I was baptised I understood the 'sign' as
'the act of God's Son in receiving authority from his Sovereign Father to rule in an everlasting kingdom. This event brought the establishment or "birth of his kingly rule.
The primary part of the composite sign being the preaching. Gathering the anointed and other sheep. Isaiah 11:10-13 and the apostle Paul showed this having fulfilment in his day with the gentiles Romans 15. In Isaiah the word is signal or standard with the idea of gathering.This gathering to the mountain of Jehovah results in the spiritual paradise (i think)
The Watchtower has on it's cover 'Announcing Jehovah's Kingdom' In 1879 C T Russell published Zion's Watch Tower and Herald of Christ's Presence and the virgin class went forward to meet the heavenly Bridegroom in 1874 believing him to be present.
The parable of the ten virgins was given as part of the answer to the question recorded at Matt. 24:3 (God's Kingdom of a Thousand Years Has Approached, WT1973 pg205)
In 1914 they expected to meet the Bridegroom in heaven at the end of the Gentile times. !874 was arrived at by the 6000 years chronology. This was moved in the 1940's to the mid seventies. When Armageddon was expected and again they would have expected to meet the Bridgroom. Both times the virgins were in error in my opinion. Also in my opinion this would nullify the preaching as any sign.
