123. The Lord attaches and joins good to the truths a person acquires, because a person cannot take goodness as though it originated with him, since it is invisible to his sight. The reason is that goodness is a matter of warmth rather than light, and warmth is not seen but felt. Consequently, when a person sees truth in his thinking, he rarely reflects on the good that flows into it from the love in his will and gives it life. A wife also does not reflect on the goodness in herself, but on her husband's inclination toward her, which depends on the ascent of his understanding to wisdom. She influences him with the goodness that is in her from the Lord without the husband's having any awareness of that influence. From this the truth now appears, that a person acquires truth from the Lord, and that the Lord joins good to that truth according as the truth is put to use, thus as a person tries to think wisely and so live wisely.
