590. 'Repenting' has regard to wisdom, while 'grieving in heart' has regard to love. This cannot be explained intelligibly except by reference to the things that exist with man, and so by means of appearances. Every idea comprising a person's thought contains something from the understanding and something from the will, that is, something from his thinking and something from his love. Any idea which does not draw something from his will or love is not an idea, for there is no other possible manner in which he can think. A kind of permanent and indissoluble marriage exists between thought and will, so that inhering within or else adhering to the ideas comprising thought are the things which belong to his will or love. This situation existing with man enables one to know, or rather seems to make it possible to form some idea of what constitutes the Lord's mercy, namely wisdom and love. Thus in the Prophets, especially in Isaiah, dual expressions for everything occur almost everywhere, the one embodying what is spiritual, the other what is celestial. The spiritual side of the Lord's mercy is wisdom, the celestial side love.
