In a final summation of Sarah’s life, the Torah tells us two things—that she was beautiful and that she had a flawless character—her two great qualities juxtaposed.
Surrounded by a group of able-bodied men, Eliezer did not appear as a helpless, weary chap begging for a drink. And Rebecca was a young woman of nobility, not a poor servant girl accustomed to lugging water from wells . . .
Be spiritual. Listen to Sarah. Listen to your body. Use it. Use your animalistic drives and earthly achievements for G-dly missions. That’s exactly what G-d wants from you.
The miracles that both Sarah and Rebecca experienced represent the power they had to draw holiness into this world and to extend that holiness beyond the boundaries of their own homes.
