It is not until 1 Peter 3 and Hebrews 11 that we are given a fuller account, one that leaves her shining with the radiance of a godly woman. She was a model of faith, as wife and mother, hand in hand with her famous husband.
It is wise to not be too harsh on others who make mistakes, especially when we don't know all the facts. (That is, always!)
(1 Peter 3 & Hebrews 11--Even as Sarah obeyed Abraham, calling him lord:/Through faith also Sarah . . . because she judged him faithful who had promised.)
