(Mark 8:12 KJV) And he sighed deeply in his spirit, and saith, Why doth this generation seek after a sign? verily I say unto you, There shall no sign be given unto this generation.
(Mark 13:30 KJV) Verily I say unto you, that this generation shall not pass, till all these things be done.
In the demented world of following John Nelson Darby, one is supposed to believe that the phrase "this generation" in the above two verses refers to two completely different generations.
Unless your in left field with Right Divider, who may claim that both verses refer to a future generation.
Either way, it's clear as day who Jesus was referring to when you don't have to defend the false teachings of John Nelson Darby.
