The Heavenly Wedding Banquet

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 said to his servants, ‘The wedding banquet is ready, but those I invited did not deserve to come. 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, both good and bad, 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. ‘Friend,’ he asked, ‘how did you get in here without wedding clothes?’ 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.”
Mt 22:1-14

In the above parable, the king who prepared a wedding banquet for his son represents God, and the son, the bridegroom, stands for Jesus. Inviting people to the wedding banquet means gathering those who will be saved and go into the heavenly wedding banquet of eternal life. So, the Bible says that blessed are those who are invited to the wedding banquet.

Then he said to me, “Write, ‘Blessed are those who are invited to the marriage supper of the Lamb.’ ” …
Rev 19:9

we need to find out who the bride, the wife of the Lamb, who has made herself ready, is.

One of the seven angels who had the seven bowls full of the seven last plagues came and said to me, “Come, I will show you the bride, the wife of the Lamb.” And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of heaven from God.
Rev 21:9-10

But the Jerusalem that is above is free, and she is our mother.
Gal 4:26

The angel said to John that he would show him the “bride, the wife of the Lamb,” and then showed him Jerusalem. Here, we can see that Jerusalem represents the wife of the Lamb. and Jerusalem is our spiritual Mother.

The Bible says, “Blessed are those who participate in the wedding banquet,” or, “Blessed are those who are invited to the wedding feast.” We can see that the blessed people, who are invited to the everlasting heavenly wedding banquet, are those who believe the truth about God the Father and also realize and believe the truth about Mother completely.
