590. That "repenting" has reference to wisdom, and "grieving at heart" to love, cannot be explained to human apprehension, save in accordance with the things that are with man, that is, by means of appearances. In every idea of thought in man there is something from the understanding and from the will, or from his thought and his love. Whatever idea does not derive anything from his will or love is not an idea, for otherwise than from his will he cannot think at all. There is a kind of marriage, perpetual and indissoluble, between the thought and the will, so that in the ideas of man's thought there inhere or adhere the things that are of his will or his love. From this state of things in man it may as it were be known, or rather it seems possible to form some idea of what is contained in the Lord's mercy, namely, wisdom and love. Thus in the Prophets, especially in Isaiah, there are almost everywhere double expressions concerning everything; one involving what is spiritual, the other what is celestial. The spiritual of the Lord's mercy is wisdom; the celestial is love.
