Gospel of Mark - Riddle Me This?

Mark 12:18-27 describes Jesus' encounter with the Sadducees, a Jewish sect denying resurrection, who try to trap Him with a hypothetical question about a woman married to seven brothers; Jesus counters by explaining that in the resurrection, people are like angels, neither marrying nor being given in marriage, and proves the reality of the resurrection by quoting God's words to Moses, "I am the God of Abraham, Isaac, and Jacob," showing God is God of the living, not the dead, thus correcting their misunderstanding of Scripture and God's power.
