9 Then one of the seven angels, who had held the seven bowls filled with the seven last plagues, came and spoke with me: “Come, I will show you the bride, the wife of the Lamb.”
The angel who was in charge of bringing one of the worst plagues on the earth [see Revelation 16:17-21] came to John to reveal the bride.
The Bride refers to the saints [Matthew 22:1-14] and the Lamb is Jesus Christ [John 1:29].
The imagery between the saints and Jesus Christ as a husband and wife shows that we are one with Christ [the Spirit of God living in us], we will be with Him for all eternity, and see Him as He is. Like a wife who leaves her old life behind to start a new one with her husband, so we are leaving this sinful world to start a new life in the new earth with Jesus Christ.
10 He then carried me away in the Spirit to a great, high mountain and showed me the holy city, Jerusalem, coming down out of heaven from God
He then carried me away in the Spirit refers to the vision that the LORD showed him of the holy city made from the hands of God coming down to the new earth.
11 arrayed with God’s glory. Her radiance was like a precious jewel, like a jasper stone, clear as crystal.
The holy city, the new Jerusalem will contain the glory of the LORD. God’s light and power will illuminate the whole city. The city will shine like precious jewels.
12 The city had a massive high wall, with twelve gates. Twelve angels were at the gates; the names of the twelve tribes of Israel’s sons were inscribed on the gates.
The huge wall and the twelve gates bring to reality that not everyone can just walk in and enter it. To have access through the gates is by being born again through faith in Jesus Christ.
the names of the twelve tribes of Israel’s sons were inscribed on the gates. The gates have the names of Jacob’s sons because through them [the 12 sons of Jacob] the children of Israel [the Jewish people] came into being. God changed Jacob’s name to Israel.
13 There were three gates on the east, three gates on the north, three gates on the south, and three gates on the west.
For the names corresponding to every three gates on all four sides read Ezekiel 48:30-34.
The new city will have access on all four sides for the saints who will come in to bring glory to the Lord.
