God’s kingdom is like a banquet, a generous celebration. The kingdom is a vineyard, with everything necessary for it to be fruitful. The invitation is still going out.

Our lives should be characterized by the joy of inviting people to the banquet God has prepared, a banquet that is both present and future. Far too often our joy has been muted. The joy in our lives of the celebration of the kingdom should be so evident that the invitation becomes compelling.

But God’s kingdom is also marked by decision. The expected are absent and the unexpected are present. Some people say they are too preoccupied to come. Others presume they belong because of history, background, church attendance, or the right label. But belonging in the kingdom is not about labels. It is about loyalty to the king. The kingdom must shape who we are.

The warning about the improperly dressed guest reminds us: invitation does not remove expectation . We cannot have the kingdom on our own terms. Grace is free—but it is not cheap. Grace invites you as you are. But it does not leave you as you are. This man wanted the celebration without the change. He wanted proximity without allegiance. He was a vineyard that did not produce any fruit.

We should be alert to the importance to the kingdom of the inclusion of those on the margins, those who we would not normally think of inviting. We should be suspicious if we look round at our gatherings and see that everyone present is like us. Beware if all the relationships we have at church are with people who we feel comfortable with. The parable is not about mission, but we need to reflect on who we are inviting to come and participate in the kingdom with us.

We must not lose sight of the theme running through both parables: judgment. We are uncomfortable with that word. Would it not be easier if God simply overlooked everything? But without judgment, salvation loses its meaning. Urgency fades. Justice evaporates. Accountability disappears.

As CS Lewis tells us often, Aslan is not a tame lion. Grace is only grace if the outcome could have been otherwise, and the significance of life depends on accountability for life. We may not like judgment, but it is a central and necessary message of both Testaments and especially of Jesus’ teaching.
