'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

6051. About the love of adulteries, about the love of ruling, about deceit, etc.

The extent to which adulteries and other sins are hellish is to be described, as here regarding adulteries, that it is [hellish] to believe that adultery is permissible, whether one commits adultery or not. Scarcely anyone today believes that they are so hellish and that adulterers cannot be saved. The reasons for this are:

1. ) heaven is marriage, and hell is adultery;

[2] 2) because marriage love descends from the marriage of good and truth, adultery from the marriage of evil and falsity;

[3] 3) because offspring are born from marriage depending on the nature of the marriage love and the infernal love;

[4] 4) In heaven they abhor adultery, because it closes heaven and opens hell wide.

[5] 5) Through marriage love a person takes on the form of love, inwardly and outwardly; through adultery the form of hell; and heavenly love is implanted solely through marriage love.

[6] 6) Marriage love is the fundamental of all loves, for when a person becomes a form of love, they become an image of the Lord; otherwise the reverse happens.

[7] 7) For that reason the delights of marriage love exceed other delights in number and in quality.

[8] 8) Heavenly joy is founded upon this love in heaven, so that in so far as anyone has this love, so far they have heavenly joy of every kind and degree.

[9] 9) Wisdom grows through marriages in the heavens, which is in place of procreation there.

[10] 10) There is doctrinal adultery in the case of preachers in hell, which differs from natural adultery, about this.

[11] 11) The reason the growth of wisdom follows in accord with the degree of chastity is that its origin is the marriage of good and truth and the marriage of the Lord with the Church; its cause comes from this. For this reason no one can be wise in spiritual matters who is an adulterer. Consequently so far as one is an adulterer, so far is he blind in spiritual matters, and so far is he inwardly a devil.

[12] 12) Therefore to love one's married partner is to do good in the Lord's eyes, for this, when it comes from a chaste heart, is to love the Lord: it communicates with the heavens, and delights the minds of angels so much that it cannot be believed.

[13] 13) There is also a certain form of intercourse, because it is an effect of love, that delights heaven in like degree when it comes from chaste love; conversely it angers them to the extent it comes from adultery.

[14] 14) Bring forward examples showing that adulterers, however morally they may have lived in other respects and devoted themselves to prayers, are hurled into hell.

[Marginal Note: The reproductive organs in both sexes interact with the inmost or third heaven, where the angels more than others have a heavenly marriage, that is to say, a marriage of goodness and truth. In a word, marriages in the heavens are most holy, on which account they must not be profaned by adulteries.]
