Luk_11:30 For as Jonas was a sign unto the Ninevites, so shall also the Son of man be to this generation.The generation could be interpreted as those who "see these things" mentioned earlier, (see preceding verses). One possible way of interpreting it, but I'm always open to correction if I see otherwise in God's Word
Luk_11:51 From the blood of Abel unto the blood of Zacharias, which perished between the altar and the temple: verily I say unto you, It shall be required of this generation.
Luk_17:25 But first must he suffer many things, and be rejected of this generation.
Why would the generation in Luke 21:32 be any different than the generation in the verses above?
Luk_21:32 Verily I say unto you, This generation shall not pass away, till all be fulfilled.
