——>It is not about sex.
Yes, it is.
Matthew 22:24Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, AND RAISE UP SEED UNTO HIS BROTHER.
BTW, the issue is not sex. It is a question about the Torah-mandated marriage (a levirate marriage) where a brother has to marry his childless dead brother's widow and have children to keep his name alive. It isn't about sex, it is about keeping the dead childless brother's name alive.
And once again I mention that this was an overcomplicated trick question posed by the Sadducees to trap Jesus.
It is not about sex but simply a question of whose wife is she who has had to marry two brothers under the law.
"So whose wife would she be?"
Jesus's answer would hypothetically be the same. "There is no marriage in heaven."
The Sadducees don't believe in the afterlife. So they weren't really interested in "whose wife will she be in heaven."
And, FWIW, the Sadducees didn't believe in angels or a spirit world, so Jesus's response about angels was a dig at the Sadducees for posing such a trick question.
Jesus was showing the Sadducees that not only was he aware that they were trying to trap him with a silly question but that their question was out of sync with their own beliefs about the afterlife (heaven and angels).
This scenario once again demonstrates Jesus's vast superiority over the so-called intelligentsia of his time. You can imagine how much they hated Jesus for making fools of them in public (which he did all the time).
Ya gotta love it.;-)
