Now Jesus Christ was announced by the angels to the shepherds as the One who solves that sin problem. He solved it by His own death. He came to die for our sin. Our sin means that we, in our basic nature, are at odds with the God of the universe. And because we’re in opposition to the God of the universe, we’re at odds with all of the laws that govern the universe, all the moral laws that should provide for our well-being if we were obeying that God. And our sin has erected a great barrier between ourselves and God.

Now there were several reasons why this message was a message of joy to the shepherds and why, in exactly the same way, it must be a message of joy to us. And the first is that it had to do with the Savior.

It was C. S. Lewis who invented the phrase, “surprised by joy.” It’s the title of his autobiography. But I suppose that if there were ever people who were supremely surprised by joy, it was the shepherds when the angels appeared in the sky to announce that on that evening in Bethlehem, a Savior had been born.

At this point I have spoken of three great miracles of Christmas: that God should become man, that He should do so by means of a virgin birth, and that Mary should have believed the angel’s announcement. But now I want to say that the last of these miracles needs to have its counterpart in us. We too need to believe the good news concerning this child, that He is the Savior sent by the Father to deliver us from sin, and that we need to commit ourselves to Him in wholehearted trust and obedience.

It is hard to think of Christmas without thinking of the two great miracles I have mentioned—the incarnation and the Virgin Birth—and yet the third of these three miracles is the greatest of all, namely, that Mary should believe the angel’s message.

The second miracle of Christmas announced to Mary by the angel Gabriel is the Virgin Birth. Strangely, this miracle was not a problem for the ancients. At least no strong opposition to its being possible has been recorded. It is only in recent times, in the earlier decades of this century, that the Virgin Birth has been discounted. It was attacked by the unbelieving liberal element in Christianity.

The announcement that Jesus should be born to Mary has several parts, all of them important: that Jesus would be “great”; that He would be “the Son of the Most High”; that He would be “holy,” that is, without sin; and that He would “reign over the house of Jacob” on the throne of David forever. But of these various parts of the announcement the greatest, without any doubt, is that the one to be born should be the Son of God. It is the greatest part of the announcement because it means that by the incarnation and birth God would Himself become man.
