Through faith even Sarah herself received strength to become a mother--although she was past the time of life for this--because she judged Him faithful who had given the promise.

Thus, for instance, Sarah obeyed Abraham, acknowledging his authority over her. And you have become Sarah's children if you do what is right and permit nothing whatever to terrify you.
