One Thing Needful

In this story we learn of two sisters.
One named Martha, and the other Mary.
It is simply amazing how children, brought up in the same home, by the same mother and father can be as different as night and day.
One may be quiet and reserved, while another is very outgoing and sociable.
One may have a very adventurous spirit, and love to explore and try new things…while the other is perfectly happy as a home body, living a very timid and conservative life.
Apparently, this was the case with these 2 sisters.
