Ninety-nine is not too old for a new life and a name change, though Abraham might have preferred to be circumcised as an infant. I’m just saying. Of course Abraham wouldn’t be the father of many nations without Sarah and even if Isaac is named for her laughing at the thought of a child in her golden years it should be noted that Abraham laughed out loud at the thought as well. But that’s the way it is when you’ve spent a lifetime waiting for a promise to come true only to be disappointed time and again. And I imagine it became more difficult after Hagar bore Ishmael for then there was no doubt as to who was to blame for Sarah’s barren womb. But somehow through all the years Abraham and Sarah endured the sideways glances and whispered comments for the sake of the promise they barely believed. When the promise came true they were just as surprised as everyone else and we are as blessed by their laughing as their believing for if God allows room for disbelief in the mind of father Abraham and mother Sarah perhaps our believing has room for the doubtful laugh.
