Blessings and curses? My usual relational language with God does not include curses.
The Bible is full of strange things—oil cruets and flour containers that never become empty and young bodies that are restored to life at a word from Jesus. Are we supposed to believe that these things happened? Maybe the ancient peoples did, but we moderns suffer under the curse of Bultmann’s lightbulb: we know why the light switches on. We are cursed by rationalities that prevent us from seeing the Bible as one overarching story in which our own lives play a key role.
One of my seminary teachers once said that if you can’t think of anything original to preach, you should tell Bible stories—they have enough power to turn people’s hearts toward God. This may not work with every text, but it certainly works with the drama and wisdom of the story of Naboth and the story of the woman who washes Jesus’ feet with her tears.
