4997. And how shall I do this great evil, and sin to God? That this signifies that thus there would be disjunction and no conjunction, is evident from the signification of "evil," and also of "sin," as being disjunction and no conjunction, namely, when good spiritual natural is conjoined with truth natural not spiritual; for they are unlike and unsuited, and tear themselves away from each other. It is said "to do evil and sin to God," because regarded in itself, evil, and also sin, is nothing else than disjunction from good. Moreover, evil itself consists in disunion. This is plain from good, for good is conjunction, because all good is of love to the Lord and of love toward the neighbor. The good of love to the Lord conjoins the man with the Lord, and consequently with all the good which proceeds from Him; and the good of love toward the neighbor conjoins him with heaven, and the societies there; and therefore by this love also the man is conjoined with the Lord; for heaven properly so called is the Lord, because He is the all in all there. [2] But with evil the reverse is the case. Evil is of the love of self and of the love of the world. The evil of the love of self disjoins the man not only from the Lord, but also from heaven; for he loves no one but himself, others only so far as he regards them in himself, or so far as they make one with him. Hence he diverts to himself the attention of all, and entirely averts it from others, most especially from the Lord; and when many in a society do this, it follows that all are disjoined, and at heart each regards the others as enemies, and if anyone does aught against him, he holds him in hatred, and takes delight in his destruction. Nor is it different with the evil of the love of the world, for this covets the wealth and goods of others, and desires to possess all that belongs to them; whence also arise enmities and hatreds, but in a less degree. In order for anyone to know what evil is, and consequently what sin is, let him merely study to know what the love of self and of the world is; and in order to know what good is, let him merely study to know what love to God and love toward the neighbor is. In this way he will know what evil is, and consequently what falsity is; and from this he will know what good is, and consequently what truth is.
