Blessed are those who are invited to the wedding supper of the Lamb

Revelation 19:1-9
Amen, Hallelujah!
For the wedding of the Lamb has come, and his bride has made herself ready. Fine linen, bright and clean, was given her to wear.
Fine linen stands for the righteous acts of the saints.
Blessed are those who are invited to the wedding supper of the Lamb! "These are the true words of God."
Praise voices from heaven, 24 elders, the four living creatures, the throne, and a great multitude.
A great shout of triumph and hymn of praise is heard from heaven.
This is not sheer純粹 vindictiveness, or gloating幸災樂禍 over the fate of others. God's people stake(股權,to risk the loss of) their lives on his truth and justice.
They rejoice to see God vindicated and militant激進 unrepentant evil overthrown.
Why?
In the Old Testament, Israel is portrayed as the wife of the Lord, so the image of the bride is a natural one here.So too is the feast.
People expected Messiah's coming to be celebrated with great banquet. John brings the two together in his lovely image of the wedding-feast of the Lamb and his faithful followers, the bride - the fine linen of her wedding- dress made from 'the good deeds of God's people'.
What happiness to be an invited guest at this wedding!
How?
Do I have good deeds to wear the fine linen?
