[2] The implications of this are that natural good of truth is not spiritual good, that is, it is not the good of faith nor the good of charity until it has been reformed. Natural good comes from parents, as stated immediately above in 3469, but spiritual good comes from the Lord. To receive spiritual good therefore a person has to undergo regeneration. At first, while this is taking place truths from a source other than genuine truth itself are allied to him, such as do not remain permanently with him but merely serve as the means by which genuine truths are brought in. Once these have been brought in, truths that are not genuine are separated It is akin to the stages through which children pass: At first they learn very many things, including those that are childish - games and so on - not to make them wise but to prepare the way for them to receive the useful things that lead to wisdom. Once they have received the latter the former things are separated, indeed they are put away. Or it is like fruit which at first is filled with sour juice before it is able to receive sweet. The sour juice, which is not the genuine, is the means by which the sweet is brought in. As the latter comes in the former is dispelled.

[3] So it is with the natural part of man's mind when this is being regenerated, for natural good is such that of itself it is unwilling to obey and serve the rational as a slave does his master but wishes to take command. To render it submissive and subservient however it is chastened by means of states of vastation and temptation to the point when its cravings die down. At that point it is moderated by means of an influx from the Lord, by way of the internal man, of the good of faith and charity, even to the point where good acquired by heredity is gradually rooted out and a new good implanted in place of it. Into this new good truths of faith are introduced, like new fibres into the human heart, along which fibres new fluid is borne in, until a new heart has slowly been developed. The truths that are borne in at first cannot come from the genuine fount of truth because evils and falsities exist within the good present previously, which is natural good. Instead they are the kind of seeming truths or appearances of truth that have some affinity with genuine truths, and through which little by little the opportunity and place for those genuine truths to insert themselves is provided. Genuine good is like the blood in blood vessels or the fluid in fibres, bringing truths along and giving them shape. The good which takes shape in this way in the natural or external man is general, structured or joined together so to speak from particular and individual facets of spiritual good coming by way of the rational or internal man from the Lord, who alone forms and creates things anew. This explains why so many times in the Word the Lord is called One who forms and Creator.
