16 The second group included in “this generation” are anointed contemporaries of the first group. They were not simply alive during the lifetime of those in the first group, but they were anointed with holy spirit during the time that those of the first group were still on earth. Thus, not every anointed person today is included in “this generation” of whom Jesus spoke. Today, those in this second group are themselves advancing in years. Yet, Jesus’ words at Matthew 24:34 give us confidence that at least some of “this generation will by no means pass away” before seeing the start of the great tribulation. This should add to our conviction that little time remains before the King of God’s King- dom acts to destroy the wicked and usher in a righteous new world.—2 Pet. 3:13.
Is this what the OP is referring to?
