I do think a lot of Christians — because they don't understand the grace narrative — get out into the world and find it very tough to navigate. I think it's because they don't understand the gospel, not because they can't answer all the theological questions.

You reject marketing apologetics like, "Christianity is better than the alternatives, so choose Christianity." Why?

Marketing is about felt needs. You find the need and then you say Christianity will meet that need. You have to adapt to people's questions. And if people are asking a question, you want to show how Jesus is the answer. But at a certain point, you have to go past their question to the other things that Christianity says. Otherwise you're just scratching where they itch. So marketing is showing how Christianity meets the need, and I think the gospel is showing how Christianity is the truth.

...One reason for this is because I think there's been a backlash. Evangelicalism has been so identified with conservative Republican values that a lot of people who might be more moderate have decided they are not religious. I've seen that happen in New York. They're moderate or liberal politically, and they feel like orthodox Christianity is so identified with conservative Republican politics that they have actually distanced themselves from the faith.
