83. With every man there are two faculties of life, called Understanding and Will. The understanding is the receptacle of truth and the derivative wisdom, and the will is the receptacle of good and the derivative love. For a man to be a man of the church these two must make a one, and this they do when the man forms his understanding from genuine truths, which to all appearance is done as by himself; and when his will is infilled with the good of love, which is done by the Lord. From this the man has a life of truth and a life of good, a life of truth in the understanding from the will, and a life of good in the will through the understanding. This is the marriage of truth and good in a man, and also the marriage of the Lord and the church in him. But concerning this reciprocal conjunction called a marriage, more will be seen in Angelic Wisdom concerning Divine Providence, Divine Love and Wisdom, and Doctrine of Life.
