Today we talk a bit about laughter in Genesis 18:1-15 & 21:1-7, as Sarah hears that news that in her old age, she is going to have a kid. Along with Abraham, (yes, they have both now received new names form God) they show hospitality to three strangers who bring them this divine good news. We then wrap up with the story of Sarah giving birth to son and naming him Isaac, whose story we will pick up in the coming chapters.
