@ Kosonen: Clinging to the org's false dogma that Jesus' words at Matthew 24:14 & Mark 13:10 have a "greater fulfilment" 2000 years later, is being self-deceptive.
1) The "good news" (gospel) about Jesus & the kingdom was preached - in the 1st century:
(Colossians 1:23) "....not being shifted away from the hope of that good news that you heard and that was preached in all creation under heaven...."
(1 Timothy 3:16) ‘He was made manifest in flesh, was declared righteous in spirit, appeared to angels, was preached about among nations, was believed upon in the world, was received up in glory.’
Who exactly did Jesus commission to carry out that 1st century "worldwide preaching work?"
(Acts 1:2,4,6,8,-9) "....after he had given instructions through holy spirit to the apostles he had chosen. While he was meeting with them, (the apostles) he ordered them: “Do not leave Jerusalem, So when they (the apostles) had assembled, they (the apostles) asked him: “Lord, are you restoring the kingdom to Israel at this time?”...But you will receive power when the holy spirit comes upon you, and you (the apostles) will be witnesses of me in Jerusalem, in all Ju·deʹa and Sa·marʹi·a, and to the most distant part of the earth.” After he had said these things, while they (the apostles) were looking on, he was lifted up and a cloud caught him up from their sight."
Yup - the 11 apostles + Paul - not rank & file Christians.
2) The events which Jesus described in Matthew 24, were a one-off, things which Jesus said would never be repeated: (Matthew 24:21) "...for then there will be great tribulation..., no, nor will occur again."
Which part of "no, nor will occur again" was so difficult for us as JW's to understand? 🤔
3) As for the "last days," Christ revealed to the apostle John who would be assigned to inform & warn the world at that time. It certainly wasn't going to be any corrupted Christian denomination's responsibility:
Revelation
11:3, 7 - I will cause my two witnesses to
prophesy for 1,260 days dressed in sackcloth.” When they
have finished their witnessing, the wild beast
that ascends out of the abyss will wage war with them and conquer
them and kill them."
Revelation 14:6, 7 - "And I saw another angel flying in midheaven, and he had everlasting good news to declare to those who dwell on the earth, to every nation and tribe and tongue and people. He was saying in a loud voice: “Fear God and give him glory."
Neither of these inspired accounts point to any human organization's involvement - especially not JW's.
