122. 5. From the marriage of good and truth that emanates and flows in from the Lord, a person acquires truth, to which the Lord joins good, and in this way the church is formed in the person by the Lord. A person acquires truth from the good and truth that emanate as one from the Lord, because he receives it and assimilates it into himself as if it were his own; for he thinks of truth as though it originated with him, and he speaks from truth in the same way. This comes about because truth is seen in the light of the understanding and is therefore visible to him; and he does not know the origin of whatever he sees inside himself or in his mind, since he does not see it flowing in like the phenomena that strike the vision of the eye. Consequently he supposes that truth exists in him.
This appearance has been granted to people by the Lord in order that they may be human beings and have the means of reciprocating necessary for conjunction.
In addition, man is born with a faculty for knowing, understanding and becoming wise, and this faculty receives truths, by which he gains knowledge, intelligence and wisdom. And since the female was created through the truth of the male and is formed into a love of it more and more after marriage, it follows that she also receives her husband's truth into herself and joins it to her good.
