Since the Sadducees believed in the Law, Jesus
took them to the Burning Bush where God said,
He was "the God of Abraham, and the God of
Isaac, and the God of Jacob."

What kind of God would only be a God of a few
bones and handfuls of dust? No, Abraham and
Isaac and Jacob are alive in paradise. Luke 16:
22,23
"And it came to pass, that the beggar died, and
was carried by the angels into Abraham's
bosom: the rich man also died, and was buried;
And in hell he lift up his eyes, being in torments,
and seeth Abraham afar off, and Lazarus in his
bosom." Abraham's bosom refers to Paradise.
