5965. And came into the land of Canaan unto Jacob their father. That this signifies a dwelling where there was natural good but not spiritual good, is evident from the signification of the "land of Canaan," as being the church (n. 3686, 3705, 4447, 4517, 4736), thus the dwelling of those who represented the church, who, it is known, were the descendants of Jacob; and from the representation of Jacob, as being natural good (n. 3305, 3659, 3775, 4009, 4073, 4234, 4538), but not spiritual good, for this is represented by Israel (that Jacob represents the external of the church and Israel the internal, see n. 4286, 4570). Whether you say natural good, or the external of the church; and whether spiritual good, or the internal of the church, it is the same; for natural good constitutes the external of the church, and spiritual good the internal of the church.
 That is called spiritual which is in the light of heaven, for that which is in this light has in it the affection of good and the perception of truth. These are in this light because this light is from the Lord; and therefore they who are in spiritual good and truth are in the internal of the church, for as to their heads they are within heaven. But that is called natural which is in the light of the world, and that which is in this light has no affection of good and perception of truth in itself, but out of itself; for the light of heaven flows in and illumines what is round about; thus what is without, not what is within; and causes good to be known as good and truth to be known as truth because it is so said, and not because it is perceived to be so; and therefore they who are in natural good are in the external of the church, for as to their heads they are not in heaven, but their heads are illumined thence from without. Jacob is now called "Jacob," not "Israel," for the reason that now they are in externals; as is plain from what has been said above.
