'The spirit of God,' as in Genesis 1:2, signifies the divine mercy of the Lord.

'The spirit of God' denotes good from an interior level, so from the divine. The spirit of God is what proceeds from the divine, so from good itself, because the divine is good itself, and what proceeds from it is truth within which is good. This is what 'the spirit of God' signifies in the Word, because the spirit itself does not proceed, but the truth itself within which is good, the spirit being the instrument which produces it.

436. 'Her son whose name she called Seth' means new faith, through which charity may be received. This is clear from what has been stated already and also from where Cain is spoken of as having 'a sign placed on him lest anyone should kill him'. In the present context the meaning is this: Faith separated from love was meant by 'Cain', charity by 'Abel'. The annihilation of charity by separated faith was meant by Cain's killing Abel, and the preservation of faith, for the reason that through it charity could be implanted by the Lord, was meant by the statement about 'Jehovah putting a sign on Cain lest anyone should kill him'. After that, the Lord's conferment, through faith, of the holiness of love, and of good deriving from it, was meant by 'Jabal whom Adah bore'; and the conferment of the spiritual manifestation of faith by 'his brother Jubal'; and the existence of natural good and truth from these is meant by 'Tubal-cain whom Zillah bore'. These two verses conclude and so summarize all these matters; 'the man and his wife' means that new Church which was earlier on called Adah and Zillah, while Seth means faith through which charity is implanted. In the next verse Enosh means charity that has been implanted through faith.
