SYG teaches HM molded the attributes of Abraham in the preexistence.

I protest against arguing that his [Abraham] mother or her outward circumstances shaped and molded the grand character of Father Abraham. No, indeed, our great heavenly Mother was the great molder of his [Abraham's] spirit and his individuality. His earthly mother has much to do with his little earthly manners, habits, ways or characteristics, if that will better express my meaning, and his training both during the nine months before his birth and for the ten years after his birth had much to do with his earthly career.
