I do agree with Dr Blomberg, if us as Christians want to bring change to our world, it has to be by being completely different from the world. The world has enough violence, Jesus said all will know that you are my disciples if you love one another. Love was the catalyst for change. When Jesus was on Earth, He expelled demons from people, because the kingdom of Heaven was here on Earth. One kingdom replaced another, the better and the more powerful was replacing the broken one. Change comes from something radical and different to oppose what has been stablished before.
