There is knowledge of God and the spiritual nature of man, as well as other types of reality..., that are not reducible to the world dealt with by the so-called "natural" sciences. The idea that knowledge - and, of course, reality - is limited to that world is the single most destructive idea on the stage of life today.
Dallas WillardTwo ways of thinking: Human kingdom and human cleverness or God's kingdom and God's cleverness
Dallas WillardThe world can no longer be left to mere diplomats, politicians, and business leaders. They have done the best they could, no doubt. But this is an age for spiritual heroes- a time for men and women to be heroic in their faith and in spiritual character and power. The greatest danger to the Christian church today is that of pitching its message too low.
Dallas WillardSo when Jesus directs us to pray, “Thy kingdom come,” he does not mean we should pray for it to come into existence. Rather, we pray for it to take over at all points in the personal, social, and political order where it is now excluded: “On earth as it is in heaven.” With this prayer we are invoking it, as in faith we are acting it, into the real world of our daily existence
