The outline of the story is pretty simple; the meaning is pretty clear. A king is preparing a wedding feast for his son. The king much earlier honored his guest list with the invitation, and the people appropriately responded with a promise to come; the second invitation in the parable is merely to inform them that the feast is now ready and it is time to come. But then, the plot takes an unexpected turn. Amazingly, when the dinner party is ready, and everyone on the invitation list contacted, nobody comes to the party. They all make excuses. We're familiar with this sort of thing, aren't we?
Of course, this parable is not actually about a wedding party. This is about the invitation to God's feast; that is, about the invitation to salvation we have received through Jesus Christ. This parable is a clear warning to all of us: so many good things can capture our attention and time that we miss our opportunity to come to God's salvation. And equally important is the clear expectation that we will be part of making the invitation to ever-widening circles of people. Missional community means living the God's Kingdom life and inviting others to join us.
