The whole of heaven and its individual inhabitants without exception trace their origin to the Lord alone, in general and in the smallest particulars. This is the source of order, of unity, of mutual love, and of happiness, because this is what causes individuals to look to the health and happiness of all, and all to that of every individual.
Many experiences have shown me that all joy and happiness in heaven come from the Lord alone. At this point, let me recount just one such experience.
I saw that certain angelic spirits, using the greatest possible care, were making an ornate lampstand, with its lamps and flowers, in the Lord’s honor. For an hour or two I was allowed to observe how hard they worked to make absolutely everything beautiful and full of significance. They felt that the labor was their own, but I was able to sense clearly that they could invent nothing by their own power.
Finally, several hours later, they said they had succeeded in making a gorgeous lampstand, with all its representative art, in honor of the Lord, and at this they rejoiced from the depths of their being. I told them, however, that at no time had they designed or created anything on their own but that it was the Lord alone who had done this for them. At first they were scarcely willing to believe it, but being angelic spirits, they received enlightenment and confessed that it was so.
The same is true for all their other representative objects, for all their feelings and thoughts without exception, and so for heavenly joy and happiness; the least of them all come from the Lord alone.
