Mary, the mother of Jesus was a relative of Elizabeth, the mother of John. After the angel appeared to Mary telling her of the coming of Jesus, she went to see Elizabeth and learned that she, too, was expecting a child. Now Elizabeth and her husband Zechariah were advanced in years and their child was a very special child. He had been chosen by God for a special mission. That mission was to prepare the hearts of the people for the coming Messiah. The prophet Isaiah spoke of John as "the voice of one crying in the wilderness" telling the people to get ready for the coming of Jesus. John told them that Jesus would be greater and mightier than he, and that he was not worthy to loosen the straps or even carry the sandals of the Lord.
