80. Nothing that a person only thinks, not even what he thinks to will, is appropriated to him unless he also wills it so that he does it when opportunity offers. For when a man then does it, he does it from the will by the understanding or from affection of the will by thought of the understanding. If it is something thought only, it cannot be appropriated, for the understanding does not conjoin itself to the will, or the thought of the understanding to the affection of the will, but the latter with the former, as we have shown many times in the treatise _Divine Love and Wisdom,_ Part V. This is meant by the Lord's words, Not that which enters the mouth renders a man unclean, but that which goes forth from the heart by the mouth renders a man unclean ( Mt 15:11, 17, 18, 19). In the spiritual sense thought is meant by "mouth," for thought is spoken by it; affection which is of love is meant by "heart"; if the man thinks and speaks from this he makes himself unclean. In Luke 6:45 also by "heart" an affection of love or of the will is meant, and by "mouth" the thought of the understanding. 81. Evils which a man believes are allowable, though he does not do them, are also appropriated to him, for the licitness in thought is from the will, as there is assent. When a man deems an evil allowable he loosens the internal bond on it and is kept from doing it only by external bonds, which are fears. As his spirit favors the evil, he commits it when external bonds are removed as allowable, and meanwhile is committing it in spirit. But on this see _Doctrine of Life for the New Jerusalem,_ nn. 108-113. 82. (iv) _A man is reformed and regenerated by the Lord by means of the two faculties and cannot be reformed or regenerated without them._ The Lord teaches that, Unless one is born anew, he cannot see the kingdom of God (Jn 3:3,5,7). Few know what it is to be born anew or regenerated. For most do not know what love and charity are, therefore what faith is, either. One who does not know what love and charity are cannot know what faith is because charity and faith make one as good and truth do, and as affection which is of the will, and thought which is of the understanding, do. On this union see the treatise _Divine Love and Wisdom,_ nn. 427-431; also _Doctrine for the New Jerusalem,_ nn. 13-24; and above, nn. 3-20. 83. No one can enter the kingdom of God unless he has been born anew for the reason that by heredity from his parents he is born into evils of every kind, with the capacity of becoming spiritual through removal of the evils; unless he becomes spiritual, then, he cannot enter heaven. To become spiritual from being natural is to be born again or regenerated. Three things need to be considered if one is to know how man is regenerated: the nature of his first state, which is one of damnation; the nature of his second state, which is one of reformation; and the nature of his third state, which is one of regeneration.
