as Sarah obeyed Abraham, calling him lord, whose children you now are, if you do well, and are not put in fear by any terror.
calling him lord: Reference is made to Genesis 18 as an illustration of Sarah’s position and faithfulness. She recognized the position of her husband, entertained the highest respect for him, left her home in Ur, and lived in tents for years because she was following his leading; she indeed assumed her proper sphere in the home. Peter says this is an exemplary life for those who are sisters in Christ.
