When my house elf* married her Christian husband (many years ago) she became a Christian. As she was being counselled by the pastor's wife about Christianity her questions were not "Is Christianity true?" or "How do I know that God is real?" it was "What do Christians do?"
She explained "We Hindus get up in the morning and do puja before anything else, we burn incense and we don't eat beef - what do Christians do?"
Much of evangelism in Australia tends to be the more intellectual questions - Is Christianity true? What does the Bible say?
Maybe my house elf's questions are also reflected in the hearts of Australians too? Lots of people know what Christians DON'T do, but do they know what they DO do? Maybe our evangelism in Australia should also be directed towards answering the more practical question. How is my life, in a very practical sense, different (and better) as a Christian?
* My house elf is paid a decent wage, is not bound to the house, and is also not an elf.
