Jesus answered and spoke again in parables to them, saying, "The Kingdom of Heaven is like a certain king, who made a marriage feast for his son, and sent out his servants to call those who were invited to the marriage feast, but they would not come. Again he sent out other servants, saying, 'Tell those who are invited, "Behold, I have prepared my dinner. My cattle and my fatlings are killed, and all things are ready. Come to the marriage feast!"' But they made light of it, and went their ways, one to his own farm, another to his merchandise, and the rest grabbed his servants, and treated them shamefully, and killed them. When the king heard that, he was angry, and sent his armies, destroyed those murderers, and burned their city. "Then he said to his servants, 'The wedding is ready, but those who were invited weren't worthy. Go therefore to the intersections of the highways, and as many as you may find, invite to the marriage feast.' Those servants went out into the highways, and gathered together as many as they found, both bad and good. The wedding was filled with guests. But when the king came in to see the guests, he saw there a man who didn't have on wedding clothing, and he said to him, 'Friend, how did you come in here not wearing wedding clothing?' He was speechless. Then the king said to the servants, 'Bind him hand and foot, take him away, and throw him into the outer darkness; there is where the weeping and grinding of teeth will be.' For many are called, but few chosen." -Jesus Christ — Matthew 22:1-14
This parable is about the king who sent out for people to come to his wedding feast, but nobody saw importance and came. In a last ditch effort, he gathered people from all over to come, whether he knew them or not. "Many were called" is the key phrase here. One man decided not to where the wedding clothing. He was called, but did not do what the king requested. He was thrown to the outer darkness, because he was not worthy of this feast. This gives us insight into what happens after we leave this world in death.
In death, we report to Jesus. He has called us many times to follow Him. On judgment day, will we be wearing our wedding clothing to celebrate Jesus' marriage to His people? The wedding clothing is our robe of righteousness, as created by the Word and wrapped around us by the Holy Spirit.
