Today as much as ever, people need to know that this kingdom is real and available. They need to see the joy and the possibilities of that kingdom in us. Because often people are too easily satisfied just to make do with what is quick and easy and cheap. People settle for sex or liquor or a rock band or the distractions provided by entertainment. They look to these things to save them, or at least to help them move forward in a grim world. But, as C.S. Lewis once wrote, we are far too easily satisfied. We're like a child who turns down an invitation for a day at the beach and chooses instead to stay sitting in a slum alley making mud pies just because the child really can't imagine how much better a day at the shore can be. "What could be better than making these slimy mud pies?" the child might think. Ah, if only he knew!
Or as Dallas Willard writes, when he was a boy, rural electrification was just happening and power lines were being strung throughout the countryside. But suppose even after the lines were up and running, suppose you ran across a house where the weary family still used only candles and kerosene lanterns for light, used scrub boards, ice chests, and rug beaters. A better life was waiting for them right outside their door, they were, not far from it, if only they would let themselves be hooked into the power lines. "My friends," you could proclaim, "electricity is at hand!" But suppose they just didn't trust it, thought it was too much of a hassle, and anyway didn't believe the promises that things might be easier with this newfangled juice running into their house. "If it's all the same to you, we'll stick with the old ways."
Maybe the kingdom is like that: it's here, not far away, it's real, it is right outside your door. The kingdom of God is at hand! A heart of love can help you draw near to it. Don't be so easily satisfied with the temporary pleasures of sex and money, power and food, cable TV and the wonders of technology. A better, exciting, hopeful, joyful kingdom of life is real. We need to be in the business of driving away the demons of doubt, despair, cynicism, arrogance, and anything else that hinders people from believing our message and so entering Jesus' kingdom. The kind of unclean spirits Jesus so routinely encountered have not gone off duty, my friends. Just look around. It is because they remain so real and powerful that we must proclaim and also live under the rule of God right now. The kingdom of God is at hand. We live knowing that this is true! We live to help others believe it, too.
