Apocalypse Explained#241
241. (Revelation 3:18) I counsel thee. That this signifies the means of reformation of those who hold the doctrine of faith alone, is evident from the things that now follow; for the reformation of those who are in that doctrine is now treated of; hence, I counsel thee, involves precepts how they ought to live in order that they may be reformed, and so be saved.
Arcana Coelestia#1413
1413. 'To the land which I will cause you to see' means the spiritual and celestial things that were to be brought to view. This is clear from the meaning of 'a land', 662, 1066, and indeed from the meaning here of 'the land of Canaan' which represents the Lord's kingdom, as becomes clear from many places in the Word. For this reason the land of Canaan is called the Holy Land, and also the heavenly Canaan. And since it represented the Lord's kingdom, it also represented and meant the celestial and spiritual things that belong to the Lord's kingdom, and here those that belong to the Lord Himself.
