Jeusu said to them, “Is this not the reason you are wrong, because you know neither the Scripture nor the power of God? For when they rise from the dead, they neither marry nor are given in marriage, but are like the angels in heaven. And as for the dead being raised, have you not read in the book of Moses, in the passage about the bush, how God spoke to him, saying, ‘ I am the God of Abraham, and the God of Isaac, and the God of Jacob’? He is not the God of the dead, but of the living. You are quite wrong.”
The Sadducees were pouring scorn on the idea of a man having an eternal, unfading ‘me’ (soul) which continued in heaven.
Yeshu said that they were wrong because Abraham, Isaac and Jacob – now long dead – continued to live with a self-mind as Abraham, Isaac and Jacob in God’s presence.
Further, he said they were wrong because the dead indeed have a body, but not one with attachments like our earthly body. God had the power to give us new spiritual bodies, whose self-minds would also possess a pure awareness, and thus be able like the angels to communicate with God Himself.
