The books entitled Matthew, Mark and Luke all quoted Jesus as saying that those to whom He was speaking “would not taste death” until they saw His kingdom.
At least they made sense, even if they were flat wrong. Revelations, as you say, was either written by a man in his cups and/or completely off his rocker.
You misinterpret the passage. In Matthew 24:32 (and in Mark and Luke as you mentioned) Jesus spoke the parable of the fig tree, which represents Israel. It is the generation that witnesses the rebirth of the nation of Israel that he is speaking of when he says “this generation will by no means pass away till all these things take place.”
No John was not off his rocker.
he did not make the visions up...Jesus showed them to him. John was a passive participant. all John did was write them down.
The vision does nothing but glorify Christ . The persecuted saints needed it.
What’s your excuse?
