And he said unto me: Knowest thou the condescension of God?
And I said unto him: I know that he loveth his children; nevertheless, I do not know the meaning of all things.
And he said unto me: Behold, the virgin whom thou seest is the mother of the Son of God, after the manner of the flesh.
And it came to pass that I beheld that she was carried away in the Spirit; and after she had been carried away in the Spirit for the space of a time the angel spake unto me, saying: Look!
And I looked and beheld the virgin again, bearing a child in her arms.
And the angel said unto me: Behold the Lamb of God, yea, even the Son of the Eternal Father! Knowest thou the meaning of the tree which thy father saw?
And I answered him, saying: Yea, it is the love of God, which sheddeth itself abroad in the hearts of the children of men; wherefore, it is the most desirable above all things.
And he spake unto me, saying: Yea, and the most joyous to the soul.
And after he had said these words, he said unto me: Look! And I looked, and I beheld the Son of God going forth among the children of men; and I saw many fall down at his feet and worship him.
And it came to pass that I beheld that the rod of iron, which my father had seen, was the word of God, which led to the fountain of living waters, or to the tree of life; which waters are a representation of the love of God; and I also beheld that the tree of life was a representation of the love of God.
