Now Abraham and Sarah were old and well stricken in age;
and it ceased to be with Sarah after the manner of women.....
Is any thing too hard for the LORD?
At the time appointed I will return unto thee,
according to the time of life, and Sarah shall have a son.
Genesis 18:11,14
As Sarah was considered to be barren as for reproducing offspring-Isaac was born from her....so too Christ rose from the barren earth.
