“I think to some extent that movement has faded out a bit,” Brierley said. “I don’t think it’s got the same cultural capital that it once had about 10 or 15 years ago.”

The worldwide conversation, he added, “has changed” to a new objection: whether Christianity is needed at all in society.

Brierley labels this new objection as one of the greatest challenges facing today’s church.

“People are less interested in asking whether Christianity is true, or whether God exists,” Brierley told Christian Headlines. “The younger generation is more concerned in asking whether Christianity is good for us [or] whether it’s harmful. … And to that extent, I think Christians can sometimes be answering questions from yesterday rather than questions from today in our apologetics.

“So I think the church really needs to make a defense of why being a Christian is good for you, why it’s good for society, even if some of the moral values or beliefs or ethics we may hold are at odds with the current sort of culture.”

Otherwise, he said, “we are in danger of simply looking irrelevant, or perhaps simply old-fashioned when actually I believe Christianity is always relevant.”

In a world filled with name-calling and derision, Brierley added, it is essential that Christians speak the truth in grace.

“Everything we do when we present people with a biblical worldview needs to be done in grace and love, as well as truth,” he said. “And that’s the challenge, I think, for the church is how to take that message, which doesn’t change, and [then] present it in gracious and truthful ways for today’s generation.”

“That’s where conversations like Unbelievable? can help. We try to model [grace] for today’s culture,” he said.
