Behold a virgin

“Behold a virgin shall conceive and bear a son, and his name shall be called Emmanuel, translated (God is with us).” Isaiah 7:14.
On Christmas Day, “a child is born to us, a son is given to us, and the government is upon his shoulders; and his name shall he called Wonderful Counselor, God the Mighty, the Father of the world to come, the Prince of Peace . . . He shall sit upon the “throne of David and upon his kingdom, to establish it and to strengthen it with judgment and with justice, from henceforth and forever.” Isaiah 9: 6-7.

THE ANGELS

‘In the beginning God created the heavens and the earth’ (Gen.1:1). Traditionally these verses of the Bible are understood as pointing to the two worlds created by God — one invisible, spiritual and intelligible, and the other visible and material. We have already said that there are no abstract concepts in biblical language and spiritual realities are often expressed by the word ‘heaven’. Christ speaks of the Kingdom of heaven, and in the Lord’s prayer we say, ‘Our Father Who art in heaven... Thy will be done, on earth as it is in heaven’ (Matt.6:9-10). It is obvious that reference is not being made to visible material sky. The Kingdom of God is a spiritual, not a material, Kingdom in which God abides, for by nature He is Spirit. And when we read that He ‘created the heavens’, this means the spiritual world and its inhabitants, the angels.
