Q. If it was such a great and unique achievement for Avraham Avinu to keep mitzvos, how come that Rachel and Leah who grew on Lavan's house were able to do the same when they were so young?
A. Horav Shlomo Miller's Shlit'a opinion is that it was the great Midos Tovos and exceptional good character they had, that made all the difference. (See other responses in 'That Is My Answer' on this Parsha).
