Neill Hamilton, who taught at Drew University for many years, once observed how people in our time lose hope for the future. It happens whenever we let our culture call the shots on how the world is going to end. At this stage of technological advancement, the only way the culture can make sense of the future is through the picture of everything blowing up in a nuclear holocaust.
The world cannot know what we know, that everything has changed in the death and resurrection of Jesus, that the same Christ is coming to judge the world and give birth to a new creation. And so, people lose hope. As Hamilton puts it: This substitution of an image of nuclear holocaust for the coming of Christ is a parable of what happens to Christians when they cease to believe in their own eschatological heritage. The culture supplies its own images for the end when we default by ceasing to believe in biblical images of God's triumph at the end.
The good news of the gospel is this: when all is said and done, God is going to win.
