Arcana Coelestia #60
60. Verse 31 And God saw everything that He had made, and behold, it was very good. And there was evening, and there was morning, a sixth day.
This verse says 'very good', whereas previous verses merely said 'good', for now the things of faith make one with those of love. A marriage has accordingly taken place between spiritual and celestial things.
Arcana Coelestia #10168
10168. Love that is indeed conjugial is a union of two minds, and this is a spiritual union. Any spiritual union comes down from heaven; therefore love that is indeed conjugial springs from heaven and its very existence (esse) can be traced back originally to the marriage of goodness and truth there. The marriage of goodness and truth in heaven has its origin in the Lord, which explains why in the Word the Lord is called Bridegroom and Husband, and heaven or the Church is called Bride and Wife. It also explains why heaven is compared to a marriage.
