What are the biggest intellectual threats to the Christian faith?

How can we expect our kids to survive going to school with their faith in tact? How can any of us hope to continue believing in Jesus when we are surrounded by such a hostile culture? Where our faith is viewed as a crutch, the Bible is thought to be an irrelevant old dusty book—just ancient superstition and mythology—where Christianity is mostly seen as being judgmental and intolerant, where morality is thought to be situational, where everyone is supposed to find their own truth, where people think they can be good without God, and Jesus was just an interesting man who died a long time ago—like Elvis.

How do we tell truth from lies? Is there a way?
