The Lord said to Abram, "Go from your country and your kindred and your father's house to the land that I will show you."
In this week's readings, we hear the call of Abraham (still known as Abram) to leave everything he had ever known in Haran and head out to seek "the land that [Yahweh} would show".
We don't learn of any reason that Abram would have to leave his homeland. He probably had many reasons to stay. He was incredibly old, for starters. Also, in a kinship-based society of the Middle East, leaving the intricate web of family relationships would be seen as foolhardy at best. He did take some family with him -- his wife Sarai and his nephew Lot. But mostly then, they were on their own.
What is your own personal Haran -- the place where you are comfortable and secure, which girds you around with support and relationship? Has God ever called you to step away from that place? Why would God want you to go? Would you be willing to go from there, if God wanted you to? What would it cost you to leave that place of comfort? What would you gain by going?
