1. Watchtower has inserted "spiritual" into Matthew 24:45 going beyond what is written. You accuse trinitarians of saying God the Father, God the Son, God the Holy Spirit, which is not in the Bible, yet turn around and insert "spiritual" into Matthew 24:45. This is a blatant double standard.
2. There is not one Scripture in the Bible that says Jesus came in 1914 visibly or invisibly.
3. There is not one Scripture in the Bible, which says God inspected the Jehovah's Witness organization and found them to be the only ones doing God's will. That is pure HOGWASH, and has no Biblical basis, only pure opinion and speculation.
God does not communicate directly with any human being. His will is made known to man through His word.
No man has a direct line to God where God gives them private interpretation. Many have claimed such a thing, and all were found to be liars. Joseph Smith, Harold Camping and Ellen White are good examples. Watchtower is no different. All are false prophets
Where is the hard evidence that Jesus came and inspected the JW organization in 1914??
There is no evidence. The Watchtower has thrown together a loosely organized group of prophetic Scriptures, and has used them to claim Jesus came in 1914. In the end, there is no Scriptural evidence, only speculation and grandiose claims.
