The Sadducees were in cahoots with the chief priests and scribes and the Pharisees.  Each of these groups of religious leaders was working to trap Jesus.
  What irony!  The Sadducees did not believe in resurrection – of no one!
  Yet, to trap Jesus their fabricated story and question was the exact opposite of their beliefs.  Hypocrisy!

  The scribes and chief priests had used legality as the basis of their question to trap Jesus.  They failed.
  The Sadducees used religiosity next to try to entrap Jesus.

(NIV) Luke 20:27-33 “Some of the Sadducees, who say there is no resurrection, came to Jesus with a question.  28‘Teacher,’ they said, ‘Moses wrote for us that if a man’s brother dies and leaves a wife but no children, the man must marry the widow and have children for his brother.  29Now there were seven brothers.  The first one married a woman and died childless.  30The second 31and then the third married her, and in the same way the seven died, leaving no children.  31Finally, the woman died too.  33Now then, at the resurrection whose wife will she be, since the seven were married to her?’”

  Question: How do we set “traps” for others?  How do we manipulate others so our agendas will be accomplished?
  Do we use legalities?  Or perhaps, we use religiosity and sound pious even when we may not believe in that point of view?  Do we set traps so others will fall flat on their faces?
  Do we look hard to find another’s “weak spot” and then pounce with an “‘Aha!’ caught you!” 
  To put another down, are we trying to make ourselves look righteous, pious, a person without flaws?

When you question another — what is your motive?
