187. "'Behold, I am coming quickly.'" (3:11) This symbolizes the Lord's advent, and a new church then formed of the people here described.
The Lord said here, "Behold, I am coming quickly," because the declaration just before this means the Last Judgment, and the Last Judgment is also called the coming of the Lord, as in Matthew,
(The disciples said to Jesus,) "...what will be the sign of Your coming and of the end of the age?" (Matthew 24:3)
The end of the age is the final period of the church, at which time the Last Judgment takes place.
This statement, "Behold, I am coming quickly," also means a new church, because after the Last Judgment the Lord establishes a new church. This church now is the New Jerusalem, into which will come people who are governed by truths springing from goodness derived from the Lord - the people to whom this announcement is addressed.
