“I believe we are at verse 23 right now. “
You don’t think that v.23 refers to the whole church age, Matthew 21:33-46?
Here’s what I think.
Luke 14:17-21a was the initial call 2000 years ago to the Jews to whom Jesus was first called, but the Jews rejected God’s offer to “Come and dine” with him.
Verse 21b-22 has been the last 2000 years of God turning to the Gentiles who have gladly “heard him”, being the recipients of Gods love and grace.
Verse 23 is the Holy Spirt saying “There is still room”. The last worlwide sweep of God’s love and grace around the world to bring as many as will come before the unimagainable begins.
