There was a certain King who gave a great feast upon the occasion of his son’s wedding. And he sent out his servants to bring in those that had been invited, but they would not come. Then he sent forth other servants saying, “Tell them which were bidden, ‘Behold, I have prepared my dinner; my oxen and my fatlings are killed, and all things are ready. Come unto the feast.'” But they made light of the message and went their ways, one to his farm, another to his warehouse; others took the servants and slew them.
When the King heard what had been done, he was very angry, and sent out his army to destroy the murderers, and burn up their city. Then said he to the servants, “The wedding is ready, but they which were bidden were not worthy. Go ye therefore into the highways, and all ye shall find, bid them come to the marriage.” So they gathered together as many as they could find. And upon each one, as he entered the house, was put a beautiful marriage garment, which the King had prepared. But when the people were all seated, and the King had entered the house, he saw there was a man that had not a wedding garment, and he said unto him, “Friend, how camest thou in hither without a wedding garment?” And the man was speechless, for the garment had been offered to him at first, but he had refused it. Then said the King to the servants, “Bind him hand and foot, and take him away and cast him into outer darkness.”
In this parable, the King means God, who gave the feast for His Son, Jesus Christ. Those who were first asked were the Jews, who refused to believe in Christ. Those who were afterwards brought in, signify the people who have since listened to His Word, and believed in Him. The one without the wedding garment is any one that pretends to accept the invitation to be one of God’s people, but in his heart does not believe in Christ.
