Missionaries supported by my church, Dave and Eowyn Stoddard, serve in Berlin. I urge you to pray for them and read this remarkable post on what Eowyn calls the bullying of demons. She writes:

Satan was not playing fair. Now the shock turned to anger. I scanned the recesses of my brain. What had seminary taught me about demonic activity? I couldn’t recall any class where we had discussed anything remotely similar to what we were experiencing. “Demonology 101” wasn’t even offered! But seminary did teach me not to panic in the face of theological conundrums. It gave me a lens through which I could see everything from the perspective of God’s sovereignty.
