Luke Chapter 1
What struck me in Chap:1 was the circumstances of Elizabeth.
Elizabeth was barren for nearly her whole married life. In Jewish society of the time this was seen as a curse, but as it transpired Elizabeth was not in fact cursed.
Her circumstances were according to the purposes of God. She was to be the mother of the Herald of the Christ, John the Baptist.
Not only was the birth of the Christ miraculous (virgin birth), but the birth of His herald was also miraculous through the unlocking of Elizabeths barren womb.
I also note in passing the similarity between Abraham & Sarah and Zechariah & Elizabeth, as in one son, late in life according to Gods purposes.
