5965. 'And came to the land of Canaan, to Jacob their father' means the dwelling-place where natural but not spiritual good resides. This is clear from the meaning of 'the land of Canaan' as the Church, dealt with in 3705, 3686, 4447, 4517, 5136, and so the dwelling-place of those who were to represent the Church, who were the descendants of Jacob, as is well known; and from the representation of 'Jacob' as natural good, dealt with in 3305, 3659, 3775, 4009, 4073, 4234, 4538, but not spiritual good since this is represented by 'Israel'. For the representation of 'Jacob' as the external aspect of the Church and of 'Israel' as the internal, see 4186, 4570. Whether you say natural good or the external aspect of the Church, and spiritual good or the internal aspect of the Church, it all amounts to the same since natural good constitutes the external aspect of the Church, and spiritual good the internal aspect of the Church.
[2] The expression 'spiritual' is used to describe that which is in the light of heaven, for what is in that light has the affection for good and the perception of truth within itself. Such affection and perception make use of that light because that light comes from the Lord. People therefore who have spiritual good and truth within themselves are in the internal part of the Church, for their heads are up in heaven. But the expression 'natural' is used to describe that which is in the light of the world, for what is in this light does not have the affection for good or the perception of truth within itself, only outside itself. For the light of heaven flows down and shines round about it, thus outside it but not within it, with the result that the person can know that good is good or truth is truth because it is said to be good or truth but not because he perceives for himself that it is such. People therefore who have only natural good within themselves are in the external part of the Church, for their heads are not in heaven. Instead what light their heads receive from heaven comes from without. Jacob is called Jacob, not Israel, at this point for the reason that they are engrossed in external interests, as is plain from what has been stated above.
