The baby we read about at the beginning of the New Testament is the Creator we read about at the beginning of the Old Testament.
Micah 5:2 (KJV)
2 But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.
