hard
Genesis 18:14
18:14 hard. “Hard” is the same word as “wonderful,” one of the terms used to describe the coming Messiah in Isaiah 9:6. God gave Sarah the faith to believe He could accomplish this wonderful miracle of rejuvenating her body, partly by letting her know He could hear her laugh even when she was out of His sight, and only laughed “within herself” (Genesis 18:12).
