In studies asking why young people left their family religion, their most frequent response was unanswered doubts and questions. The researchers were surprised: They expected to hear stories of broken relationships and wounded feelings. But the top reason given by young adults was that they did not get answers to their questions.

I began asking, 'How can we know Christianity is true?' Sadly, none of the adults in my life offered an answer. Eventually I decided Christianity must not have any answers, and I became an agnostic.

'Biblical worldview'. The term means literally a 'view of the world', a biblically informed perspective on all of reality. A worldview is like a mental map that tells you how to navigate the world effectively. It is the imprint of God's objective truth on our inner life.

Because a human is a someone and not a something, the source of human life must also be a Someone - not the blind, automatic forces of nature, as philosophies like naturalism and materialism tell us.

I discovered that Christianity does have the resources to meet the challenges posed by competing worldviews after all.

An idol is not necessarily something concrete, like a golden calf. It can also be something abstract, like matter. Is matter part of the created order? Sure it is. So the philosophy of materialism qualifies as an idol in the biblical sense.

The more we learn about life, the less plausible is any evolutionary theory that relies on blind, undirected, piece-by-piece change.
