Where you go I will go and where you stay I will stay. Your people will be my people and your God my God. Where you  die I will die and there will I be buried. May the Lord deal ever so  severely with me, if anything but death separates you and me. (Ruth 1:16, 17)

Imagine the difference it would make to marriages, families, business and political projects if we could be sure of that kind of cast-iron commitment from our partners and colleagues.
