Arcana Coelestia #47
47. That these words contain arcana concerning regeneration becomes additionally clear from the fact that verse 24 above spoke of the earth bringing forth 'living creatures, beasts, and wild animals of the earth', while in the verse that followed the order was different, namely that God made the wild animals of the earth first and then the beasts. Indeed a person does first produce things so to speak from himself, and continues to do so until he becomes celestial. And so regeneration begins with the external man and moves on to the internal. This is why there is a different order here, with external things coming first.
Arcana Coelestia #6273
6273. 'For Manasseh was the firstborn' means since good does indeed occupy the first place. This is clear from the representation of 'Manasseh' as good belonging to the will, dealt with before; and from the meaning of 'the birthright' as the prior and higher position, dealt with in 3325, so that 'the firstborn' is the one who occupies the first place. Is anyone incapable of seeing from natural light alone, provided a superior light brightens it a little, that good occupies the first place, as also do the intentions in a person's will, and that truth occupies the second, as also do the thoughts in his mind? Is anyone also incapable of seeing that the intentions in a person's will cause him to think in one particular way and no other, consequently that the good he possesses causes him to think that this or that is true; so that truth occupies the second place and good the first? Think and reflect on whether truth that composes faith can take root anywhere else than in good, or whether faith other than that which has taken root there is faith. From this you will be able to decide which is the primary or essential element for the Church, that is, for the person in whom the Church exists.
