52 in 52 Week 13: The House Church Book by Wolfgang Simson
I had read his Houses that Change the World in 2009, and I didn't care for it. Not because I didn't agree with much of what he had to say, but it was so negative toward the traditional church, and it fomented intense negativity toward it in our group. I didn't like that (and the leader of the discussion didn't help it either). So, I was happy to hear that others encouraged him to revise the book without all the negativity. The result: I loved it!
I had also listened to eight lecture by him, and I had changed my mind about him too.
We read it with our Kingdom group, and it caused us to dream about what would be the components of a house church. The discussion was great and challenging. In the process, our pastor and elders said they would be open to this being an "arm" of our traditional church to give an alternative. So, it might happen.
