Revelation 19-20

Some of the first words that John recorded was to proclaim a blessing upon those who read the words of the revelation. The declaration of blessings is repeated throughout the book. In 19:9 John hears another blessing pronounced.  This one is one those who have been invited to the lamb's wedding feast. I can't help but wonder if Jesus had the parable of the feast (Luke 14:16-24) in mind when he directed the angel to speak that blessing.
It took me about 7 minutes to read this passage.
