Matthew 22:1 - 22

Jesus pictures the coming kingdom for His followers in terms of a marriage feast given by a king for his son.  None of the invited would come.  In fact, they even treated the messengers delivering the invitations cruelly.  The king, infuriated, destroyed those who mistreated his servants.  He then tasked other servants to fill the hall with guests from all walks of life, not just those normally invited to a royal banquet.  Those who refused to attend on the king's terms were barred from the festivities.

The religious leaders, still attempting to turn public opinion against Jesus, bring up a question of taxation.  Jesus instructs them to give to Caesar the things with his inscription on it; and to give to God the things with God's inscription on it.  As bearers of the image of God, we are to give Him our lives.  No wonder the leaders marvelled at His teaching and went their way!
