The marriage of good and truth can be thought of as the union between our desire for good and our understanding of how to be good. This relationship is not static but dynamic; good leads us to search for truth, and truths stand independently of our changes of state, so that we can measure ourselves against them and decide to apply them in our own lives as good. This process is the basis of human regeneration.

From childhood, we are all engaged in a struggle between our hearts and our minds, between the relatively selfish things we want and the more noble things we know are right. The more we do what we know is right, the more the Lord will slowly be able to start changing our hearts, removing the selfishness bit by bit so real love can come through. This is a lifelong process, but ultimately we can reach a state where we truly love doing what's right, and our hearts and minds can be "married" so that they can work as a united whole.

Everything in creation is a form of this marriage. In human society, it can be found in many ways. It can exist inside each person individually. It can exist between a husband and a wife, since women have gifts for receiving the desire for good and men have gifts for receiving the understanding of truth. It can be forged by a group of people as a church. And it exists between the Lord as the bridegroom and the church as a bride.

When the Bible talks about marriage, marrying, and weddings, it is also talking on a deeper level about the spiritual marriage of good and truth.

2465. Verses 31-36 And the firstborn said to the younger, Our father is old, and there is no man in the land to come to us, according to the way of all the earth. Come, let us make our father drink wine, and let us lie with him and let us keep seed alive by our father. And they made their father drink wine that night, and the firstborn came and lay with her father; and he did not know when she lay down and when she rose up. And so it was on the next day, that the firstborn said to the younger, Behold, I lay last night with my father; let us make him drink wine again tonight, and come, lie with him, and let us keep seed alive by our father. And they made their father drink wine that night also; and the younger rose up and lay with him; and he did not know when she lay down and when she rose up. And the two daughters of Lot conceived by their father.

[2] 'The firstborn said to the younger' here, as previously, means affections - 'the firstborn' meaning the affection for that kind of good, 'the younger' the affection for that kind of falsity. 'Our father is old, and there is no man in the land' means that it is no longer known what good is and what truth is. 'To come to us' means to which those affections might be joined. 'According to the way of all the earth' means according to matters of doctrine, 'earth' being the Church. 'Come, let us make our father drink wine' means that they might saturate such good with falsities, meant by the wine. 'And let us lie with him' means that in this way they would be joined together.

[3] 'And let us keep seed alive by our father' means that in this way a new kind of a Church would emerge. 'And they made their father drink wine' means that they saturated such good with falsities. 'That night' means when all things were enveloped in so much obscurity. 'And the firstborn came' means the affection for that kind of good. 'And lay with her father' means that in this way the two were brought together. 'And he did not know when she lay down and when she rose up' means that such general good knew no other than that it was so. 'And on the next day' means afterwards. 'The firstborn said to the younger' means that the affection for such good persuaded the falsity. 'Behold, I lay last night with my father' means that thus they had been joined together. 'Let us make him drink wine again tonight' means here, as previously, that they saturated such good with falsities, at a time when everything was enveloped in so much obscurity. 'And come, lie with him' means that these might be joined together as well.

[4] 'And let us keep seed alive by our father' here, as previously, means that in this way a new kind of a Church would emerge. 'And they made their father drink wine that night also' means that in that obscure state they saturated such good with falsities. 'And the younger rose up and lay with him' means that the affection for falsity acted in a similar fashion, so that falsities looked like truths, and the two were in this way joined together. 'And he did not know when she lay down and when she rose up' here, as previously, means that such a general type of good knew no other than that it was so. 'And the two daughters of Lot conceived by their father' means that this was how such a religion as that meant by 'Moab' and 'the son of Ammon' arose.

1067. Verse 20 And Noah began to be a man (vir) of the ground, and planted a vineyard.

'Noah began to be a man of the ground' means in general a person who has been instructed from matters of doctrine concerning faith. 'And he planted a vineyard' means the Church resulting from this, 'vineyard' being the spiritual Church.
