6538. 'Which is at the crossing of the Jordan' means which is one of introduction into cognitions of good and truth. This is clear from the meaning of 'the Jordan' as introduction into cognitions of good and truth, thus the first sector of the Lord's kingdom and the Church as one goes in, and the last as one comes out, dealt with in 4255. The rivers where the land of Canaan came to an end were representative of the outermost things within the Lord's kingdom, see 1585, 4116, 4240. This is why 'the crossing of the Jordan' means introduction into cognitions of good and truth, for cognitions of good and truth are what come first and serve to introduce a person into the things that constitute the Church.
