wt has never professed to be inspired although they assert to be directed by God's HS exclusively;I agree.
In an article in the October 1st 1960 Watchtower, The Holy Bible-the book by Jehovah's Witnesses on page 586 under the subheading Written under inspiration, paragraph 10 quotes Matthew 12:28 and then Luke 11:20 where Jesus expelled demons and in Luke's account it says,' ..by means of God's finger...' In the following paragraph it mentions that
'Jesus thus spoke of God's spirit as God's "finger." In a direct way God's finger wrote the Ten Commandments on the two tablets of stone. But when God used men to write the various books of the Holy Bible God's symbolic finger, his spirit, shoved the stylus or pen of these men.'
In another Watchtower 1963 page 502 in the article Understanding what the Spirit is on page 503 it says,
..we have seen the word spirit has at least seven distinct meanings.
and in the previous paragraph to this it talks of Jesus miracles and that these were done by God's spirit and quotes Matthew 12:28. It then says'
'It was the same active force that gave Samson the strength to perform astonishing deeds,...'
Further on same paragraph,
'It enveloped 120 disciples of Jesus Christ at Pentecost and made it possible for them to heal the sick and raise the dead. God's spirit was poured out upon them in this fashion, he baptizing them in it (Acts 2:17)'
The way that I understand it is that this scripture in Acts 2:17 where it talks of the pouring out God's spirit and they 'will prophesy' which verse 16 shows to be quoting from the book of Joel is fulfilled in the remnant of anointed Christians from 1919.
'The dedicated believers had been anointed with holy spirit to prophesy and preach.'(WT.1966.page 690)
As they spoke of themselves as 'commissioned to serve as the mouthpiece and active agent of Jehovah'* and are prophesying due to the holy spirit like Jesus performed miracles and the bible was written. I don't really see a difference between. Inspired and directed.
