"All those statistics - the ones about decline - point toward massive theological discontent. People still believe in God. They just do not believe in the God proclaimed and worshipped by conventional religious organizations. Some of the discontented - and there are many of them - do not know what to call themselves. So they check the "unaffiliated" box on religion surveys. They have become secular humanists, agnostics, posttheists, and atheists and have rejected the conventional God. Others say they are spiritual but not religious. They still believe in God but have abandoned conventional forms of congregating. Still others declare themselves "done" with religion. They slink away from religious communities, traditions that once gave them life, and go hiking on Sunday morning. Some still go to church, but are hanging on for dear life, hoping against hope that something in their churches will change. They pray prayers about heaven that no longer make sense and sing hymns about an eternal life they do not believe in. They want to be in the world, because they know they are made of the same stuff as the world and that the world is what really matters, but some nonsense someone taught them once about the world being bad or warning of hell still echoes in their heads. They are afraid to say what they really think or feel for fear that no one will listen or care or even understand. They think they might be crazy. All these people are turning toward the world because they intuit that is where they will find meaning and awe, that which those who are still theists call God. They are not crazy. They are part of this spiritual revolution - people discovering God in the world and a world that is holy, a reality that enfolds what we used to call heaven and earth into one. These people are not secular, even though their main concern is the world; they are not particularly religious (in the old-fashioned understanding of the term), even though they are deeply aware of God. They are fashioning a way of faith between conventional theism and any kind of secularism devoid of the divine. In our time, people are turning toward the numinous presence that animates the world, what theologian Rudolf Otto called "the Holy." They are those who are discovering a deeply worldly faith. Decades ago Catholic theologian Karl Rahner made a prediction about devout people of the future. He said they would either be "mystics," those who have "experienced something ," or "cease to be anything at all"; and if they are mystical believers, they will be those whose faith "is profoundly present and committed to the world." The future of faith would be an earthy spirituality , a brilliant awareness of the spirit that vivifies the world."
