This parable about the "kingdom of heaven" was directed to His enemies, to warn them about their impending doom.
The King in the Lord's story represents God the Father, who gave a large banquet for His Son, Jesus Christ.
Matt. 22:1-14~ PARABLE OF THE MARRIAGE FEAST OF THE KINGS SON~ 12-29-12
Let me remind us first of all that the gospel of Matthew was given primarily too the Jews, it was written by a Jew, (Matthew) to the Jews, and it tells about a Jew (Jesus) but all of us can glean from Matthews gospel.
