You are actually close. You are missing the fact that Israel is in fact, God's chosen people.
"And Jesus answering, spoke again in parables to them, saying: [2] The kingdom of heaven is likened to a king, who made a marriage for his son. [3] And he sent his servants, to call them that were invited to the marriage; and they would not come. [4] Again he sent other servants, saying: Tell them that were invited, Behold, I have prepared my dinner; my calves and fatlings are killed, and all things are ready: come ye to the marriage. [5] But they neglected, and went their own ways, one to his farm, and another to his merchandise.
[6] And the rest laid hands on his servants, and having treated them contumeliously, put them to death. [7] But when the king had heard of it, he was angry, and sending his armies, he destroyed those murderers, and burnt their city. [8] Then he saith to his servants:
The marriage indeed is ready; but they that were invited were not worthy. [9] Go ye therefore into the highways; and as many as you shall find, call to the marriage" (Matthew 22:1-9).
