1 Corinthians 15:18,19
In fact, also, those who fell asleep [in death] in union with Christ perished,. If in this life only we have hoped in Christ we are of all men most to be pitied. (NWT)
Commenting on this scripture in the book Man's Salvation Out of World Distress At Hand(1975 Watchtower), I believe we studied this book after 1975 probably 1976, it says on page 28.
So much depended upon Messiah's resurrection, and the apostle Paul had suffered so much persecution for preaching it, that if Paul were a liar, then, as he wrote...
So, too, with our generation in this twentieth century. After all that we have gone through since 1914, our generation would be, of all generations, the "most to be pitied".
Think of it, though! Worthy ones of this generation of mankind will be saved alive out of the rest of this world distress so as to survive the worst of it and enter into God's Messianic new system of things and not need a resurrection from the dead to life on earth! This is a valid hope well founded on what was said by Jesus Christ..."
It seems to link what Paul preached regarding the resurrection of Christ with the generation teaching.
The book's opening chapter and paragraph it asks the question
How much more will the present generation of mankind have to take of this world distress that has plagued us since 1914 C.E.?
and then says regarding the length of the generation
Fewer of us have attained to eighty years of age or more. In times such as these, such an age attainment is very good, according to the age-old saying tht set a reasonable time-length for a generation:
"The days of our years in this life are seventy years; and if by uncommon vigour they be eighty, yet is their greatness trouble and mishap; for it soon hasteneth off, and we fly away," *
During those seven or eight decades of our lives, oh, what we have experienced! For good reason, then, the announcement "Man's salvation out of world distress at hand! is good news indeed.
*written by Moses son of Amram, in Psalm 90:10, Leeser.
The apostle Paul preached good news concerning the resurrection of Christ. This good news about the generation that my mother heard hasn't proved to be good news.
After the disappointment of 1975 then the disappointment of the generation.
