The Gospel from Matthew 22:1-14 is one of several parables that compare the kingdom of heaven to a feast, in this case, a royal wedding feast. The king prepares the meal and invites the guests, but those invited despise the invitation. Some simply ignore it, but others attack and even kill the messengers sent to them. The king responds forcefully to such ingratitude and evil. He destroys the evildoers and seeks new guests for his feast. According to the customs of that time, the royal host even had appropriate garments provided for them. Yet, one guest refuses to be grateful and to cooperate. Although provided a garment, he does not bother to dress appropriately, and so he is cast out.
By emphasizing the gracious invitation of the king and the ungrateful responses of some guests, this parable stresses two points about the heavenly kingdom. First, the kingdom is based on the graciousness of the divine King. God always has the initiative. He invites people to His feast. He extends the offer of fellowship with Him. He provides all that is needed. Secondly, however, the invited guests are expected to respond in gratitude. People must accept the divine invitation and prepare in appropriate ways. The divine host provides all that is needed to join the celebration, but He will judge those who despise or reject His grace.
As Christians, we must keep both of these points in mind. We are dependent upon the graciousness of God. He invites us; He calls us. And He provides all that we need to enjoy His company. Nevertheless, He also expects appropriate responses from us. Refusing to accept His call and ignoring His gifts brings judgment and exclusion from His presence. So let us heed the warning, and let us accept God's invitation with gratitude!
