If you read my posts I have some good reasons to do so .
I have a prediction for 2011 AD and the period of 120 years must be recorded prior to the time when Jesus returns .
1879 AD + 120 years = 1999 AD was a good prediction .The date 1879 AD is related to the Watchtower . Then they have 1884 AD.
1884 AD + 120 years = 2004 AD- it was a good prediction that is Biblically founded .
Then they have 1914 AD .
1914 AD + 120 years = 2034 AD - a good prediction .
But it came out that there is still one more important date 1891 AD that is related to some degree to Jehovah's Witnesses as they use the date 2 BC and in 11 AD Jesus was 12-years old when began teaching in the Temple - Luke 2.42 .
He was actually 17-years old but looked like a 12-year old since the date 7 BC is used by me in calculations and it was the actual date of the birth of Jesus.
11 AD + 2000 years = 2011 AD.
1879 AD + 12 years = 1891 AD. 1891 AD + 120 years = 2011 AD.
The spiritual ark of salvation has to be built for 120 years . I was not living back then; so there must be the people of the new true christian religion who began building the ark .
The International Bible Students nicely fit the requirement .Then Jehovah's Witnesses with the name Watchtower that binds the two .
