There are some recent buzz words, especially among Lutheran circles--"sharing your story," "telling your story," and the like.I'm not a fan of buzz words or catch phrases that become their own insider lingo. But I do like the idea that these particular ones are trying to get across.
With "sharing your story," the idea seems to be that it is important for people to be able to tell about their lives, where God has shown up in their lives, how they see their lives connected to what Jesus is still doing in the world.
This is more than just "sharing" one's story, though. This is "owning it"--personally expressing how one's life has been drawn into the family of God, swept up by the Holy Spirit. Some evangelical circles used to (and still do) call it "giving your testimony." Lutheran and other circles for whom this is a new catchphrase are really just using different language to talk about the same thing that evangelicals have been doing for a long time.
