God weeps because of the sins of his children, because they reject him and are without love for one another. But if God also weeps at evil, then it is built into the universe; it is unavoidable.

If we cannot hope to permanently rid the universe of evil, then what can we hope for? For atonement.

Next week most Christians will celebrate the birth of Jesus Christ. But why? Why do we celebrate his birth? Mormons don't celebrate the birth of the prophet Joseph Smith. We don't celebrate the birthdays of other important saints except in, perhaps, a minor way. We know almost nothing about Jesus' childhood, presumably because the writers of the Gospels thought it irrelevant to the gospel message. But if Jesus' childhood is irrelevant, what makes his birth so important?

My guess is that it is because we celebrate that the Son of God, himself already divine, began his most important work as a human baby: he had the full experience of mortality just as we do; he condescended to be as we are.

The Son did not just dip his toe into the cold waters of mortality. He plunged in head first. Whatever joy or suffering we have experienced, he too has experienced it. He is not distant from us, but like us, bone and flesh. Jesus' birth is a token of the work he does: he was born as a baby, becoming a living body like our own, because his work was to redeem our souls, our living, lived bodies rather than only some immaterial thing.

We learn of Jesus' birth early in the book of Mormon, when the prophet Nephi receives the same vision that his father had earlier received:

 And it came to pass that I looked and beheld the great city of Jerusalem, and also other cities. And I beheld the city of Nazareth; and in the city of Nazareth I beheld a virgin, and she was exceedingly fair and white.

 And it came to pass that I saw the heavens open; and an angel came down and stood before me; and he said unto me: Nephi, what beholdest thou?

 And I said unto him: A virgin, most beautiful and fair above all other virgins.

 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. (1 Nephi 11:13-23)
