The angel said to them, "Don't be afraid, for behold, I bring you good news of great joy which will be to all the people.
According to the text they were not to be afraid, first of all, because “the angel had come to bring them good news.” What does it say? It says, “I bring you good news of great joy.” But what was this gospel? Further on we are told that the gospel was the fact that Christ was born. So, then, it is good news to men that Christ is born, that God has come down and taken manhood into union with Himself. Truly this is good news. He who made the heavens sleeps in a manger. What does that mean? Why it means that God is not necessarily an enemy to man, because here is God actually taking manhood into union with Deity.
