923. 21:26 And they shall bring the glory and the honor of the nations into it. This symbolically means that those who enter the New Jerusalem will bring with them a confession, acknowledgment and faith that the Lord is God of heaven and earth, and that every truth of the church and every good of religion comes from Him.

To bring glory and honor into the city means, symbolically, to confess the Lord and attribute to the Lord all the goodness that people possess, as may be seen in no. 921 above. The symbolism is the same here, with the difference that before it was people meant by the kings of the earth who would bring it with them, while here it is people meant by the nations. For we are told that they will bring the glory and honor of the nations into it, and nations symbolize people who live a good life and believe in the Lord (no. 920). The verse also refers to the reception of those who possess truths that spring from the goodness of love from the Lord, as said in no. 922 above. It follows, therefore, that the people's bringing the glory and the honor of the nations into the city means, symbolically, that those who enter will bring with them a confession, acknowledgment and faith that the Lord is God of heaven and earth, and that every truth of the church and every good of religion comes from Him.

Almost the same symbolism occurs in the following verse in Isaiah:

...I will spread peace over (Jerusalem)..., and the glory of the nations like a... stream. (Isaiah 66:12)

We say the truth of the church and the good of religion because the church is one thing and religion another. The church is called a church because of its doctrine, and religion is called religion because of its life in accordance with doctrine. Every teaching of doctrine is called truth, and the good of doctrine is also truth, because doctrine only teaches it. But every effect of a life in accordance with what doctrine teaches is what we call good. Putting the truths of doctrine into practice is also good. This is the distinction between the church and religion. But still, where there is doctrine and not life, neither the church nor religion can be said to exist, because doctrine regards life as united with it, altogether like truth and good, faith and charity, wisdom and love, and intellect and will. Consequently, where there is doctrine and not life, the church does not exist.

702. Three unclean spirits like frogs. This symbolically means that there arose nothing but reasonings and lusts to falsify truths.

Spirits here have the same symbolism as demons, since we are shortly told that they were spirits of demons, and demons symbolize lusts to falsify truths (no. 458). The number three symbolizes all (nos. 400, 505), here nothing but. Frogs symbolize reasonings prompted by lusts, because they croak and are lascivious.

It is apparent from this that three unclean spirits like frogs symbolize nothing but reasonings and lusts to falsify truths.

Frogs here have the same symbolic meaning as the frogs in Egypt, because the destruction of the church among the Egyptians is likewise described by the miracles done, regarding which we are thus told in Exodus:

Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land... (Exodus 8:5-14, cf. Psalms 78:45; 105:30)

And later the frogs were removed, remaining only in the river (Exodus 8:11-13).

Frogs were produced from the waters of Egypt and remained in the river because the waters in Egypt, and especially those in the river there, symbolized doctrinal falsities on which the people based their reasoning.
