922. 21:25 Its gates shall not be shut by day, for there shall be no night there. This symbolically means that the New Jerusalem continually receives into it people who possess truths that spring from the goodness of love from the Lord, because it has no falsity in its faith.

Its gates not being closed by day means, symbolically, that people who wish to enter are continually being let in. By day means, symbolically, continually, because there is always light then, as described in verses 11 and 23 above, and no night, as said next.

People who possess truths that spring from the goodness of love from the Lord are continually received because the light of the New Jerusalem is truth springing from the goodness of love, and the goodness of love comes from the Lord, as we have often shown above. And the only people who can enter into that light are people who possess truths that spring from goodness received from the Lord. If any others enter, they are not welcomed, because they are of a discordant character, and they then either leave of their own accord because they cannot endure that light, or they are sent away.

There being no night there symbolically means that there is no falsity in its faith, for night symbolizes the opposite of light, and light, as we have said, symbolizes truth that springs from the goodness of love from the Lord. Night therefore symbolizes something that does not spring from the goodness of love from the Lord, and that is falsity in people's faith. Falsity in people's faith is also meant by night in John:

(Jesus said,) "I must work the works of (God) while it is day; the night is coming when no one can work." (John 9:4)

And in Luke:

...in that night there will be two people in one bed: the one will be taken and the other will be left. (Luke 17:34)

The subject there is the final period of the church, when faith will have in it nothing but falsity. The bed symbolizes doctrine (no. 137).
