I think we've gotten to the point now, where everyone knows that the world needs changing. I mean, everyone. There's nobody who says, "Oh, the world's in great shape. Let's just keep it on the track it's going on. Don't even touch it. It's working so well." No, everyone knows the world needs changing. And I think the people who know it best - who know it maybe most - are parents, because they're concerned about the world their children will grow up in. Or grandparents, because I think some of them are petrified about the world their grandchildren will grow up in. The uncomfortable truth, I think, is that if Christians behaved like Christians, the world would change very, very quickly. If Christians behaved like Christians, you would transform the world radically and quickly. And it would be a transformation of joy. In the Old Testament, we read about David dancing for joy before the ark of the covenant, which, for the Jewish people, represented the presence of God. So David was dancing for joy in the presence of God. In the New Testament, we read about the child, John the Baptist, dancing for joy in the womb of Elizabeth when Elizabeth hears Mary's greeting. Why? Because even the child, John the Baptist, realizes he was in the presence of God. Because at that moment, Mary is a living tabernacle. Mary is the first tabernacle, carrying the child Jesus. And so the response of even the unborn child, of John the Baptist, is to dance for joy in the womb of Elizabeth. We're called to dance for joy. The Christian life should be joyful. People should see joy in our lives. And that joy is contagious. And that joy is what the world is yearning for. It's our job to bring that joy into the world and into people's lives.
