Schools ought to teach students to challenge secular ideologies masquerading as science in the classroom.

The gospel is like a caged lion,' said the great baptist preacher Charles Spurgeon. 'It does not need to be defended, it simply needs to be let out of it's cage' Today, the cage is our accommodation to the secular/sacred split that reduces Christianity to a matter of personal belief. To unlock the cage, we need to become utterly convinced that, as Francis Schaeffer said, Christianity is not merely religious truth, it is total truth- truth about the whole of reality.

The human mind inherently seeks intelligible order. Thus the conviction that such an order exists to be found is a crucial assumption.

Christian adults need to think about talking to our own children as a form of cross-cultural missions. Cultural change happens so quickly that teens are exposed to ideas and worldviews very different from those of previous generations.

In many churches, the message of justification- how to get right with God- is preached over and over again. But much less is said about sanctification- how to live after you're converted.

Urban areas tend to attract members of the 'knowledge class' - people who work with ideas, data, information

Modern secular thought has its own dualism: It treats only the physical world as knowable and testable, while locking everything else - mind, spirit, morality, meaning - into the realm of private, subjective feelings. The so-called fact/value split.
