This week we hear wisdom calling us to come and be satisfied, to eat what is good even though we have no money to buy it. Paul admonishes us not be foolish – to know God’s will. And Jesus tells a parable about having the right clothes for the wedding feast, so that we won’t be thrown out. But what is wisdom telling us, what is God’s will, and what are the right clothes? Fortunately, Isaiah tells us clearly: turn from your sins and receive God’s pardon – that is God’s will. In baptism we receive God’s abundant forgiveness, that only Christ could buy for us, and are clothed with Christ’s righteousness. Through God’s unfathomable mercy, we are ready for the feast!
The Old Testament lesson is from the book of Isaiah, chapter 55, verses 1-9:
“Come, all you who are thirsty,
come to the waters;
and you who have no money,
come, buy and eat!
Come, buy wine and milk
without money and without cost.
Why spend money on what is not bread,
and your labor on what does not satisfy?
Listen, listen to me, and eat what is good,
and you will delight in the richest of fare.
Give ear and come to me;
listen, that you may live.
I will make an everlasting covenant with you,
my faithful love promised to David.
See, I have made him a witness to the peoples,
a ruler and commander of the peoples.
Surely you will summon nations you know not,
and nations you do not know will come running to you,
because of the Lord your God,
the Holy One of Israel,
for he has endowed you with splendor.”
Seek the Lord while he may be found;
call on him while he is near.
Let the wicked forsake their ways
and the unrighteous their thoughts.
Let them turn to the Lord, and he will have mercy on them,
and to our God, for he will freely pardon.
“For my thoughts are not your thoughts,
neither are your ways my ways,”
declares the Lord.
“As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.
The Epistle lesson is from Ephesians, chapter 5, verses 15-21:
Be very careful, then, how you live—not as unwise but as wise, making the most of every opportunity, because the days are evil. Therefore do not be foolish, but understand what the Lord’s will is. Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit, speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ.
Submit to one another out of reverence for Christ.
The Gospel for the twentieth Sunday after Trinity is from Matthew, chapter 22, verses 1-14:
Jesus spoke to them again in parables, saying: “The kingdom of heaven is like a king who prepared a wedding banquet for his son. He sent his servants to those who had been invited to the banquet to tell them to come, but they refused to come.
“Then he sent some more servants and said, ‘Tell those who have been invited that I have prepared my dinner: My oxen and fattened cattle have been butchered, and everything is ready. Come to the wedding banquet.’
“But they paid no attention and went off—one to his field, another to his business. The rest seized his servants, mistreated them and killed them. The king was enraged. He sent his army and destroyed those murderers and burned their city.
“Then he said to his servants, ‘The wedding banquet is ready, but those I invited did not deserve to come. So go to the street corners and invite to the banquet anyone you find.’ So the servants went out into the streets and gathered all the people they could find, the bad as well as the good, and the wedding hall was filled with guests.
“But when the king came in to see the guests, he noticed a man there who was not wearing wedding clothes. He asked, ‘How did you get in here without wedding clothes, friend?’ The man was speechless.
“Then the king told the attendants, ‘Tie him hand and foot, and throw him outside, into the darkness, where there will be weeping and gnashing of teeth.’
“For many are invited, but few are chosen.”
