38. Sexual and conjugial love are both mentioned, because sexual love is not the same as conjugial love. Sexual love belongs to the natural man, conjugial love to the spiritual man. The natural man loves and desires only outward union and the bodily pleasures it gives. But the spiritual man loves and desires inner union and the delights of the spirit it gives, and he perceives that these are only possible with one wife, with whom the degree of union can perpetually increase. The more the union increases, the more he feels delights rising in the same scale, and lasting for ever. But the natural man never thinks of this. This is how it is that we say that conjugial love remains after death with those who reach heaven, those, that is, who become spiritual on earth.
