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 WillardThe basic question 'will I obey Christ 's teaching?' is rarely taken as a serious issue. For example, to take one of Jesus' commands, that is relevant to contemporary life, I don't know of any church that actually teaches a church how to bless people who curse them, yet this is a clear command.
