Christian actor Kevin Sorbo defended his faith and has questioned atheism.

Sorbo questioned why some atheists are offended by Christian symbols that they do not believe in.

"It's funny how they can get nativity scenes pulled down because they say it offends them but they're offended by something they don't believe in," he told Access Hollywood Live.

"What offends 90 per cent of the country is that they take down nativity scenes but apparently the majority doesn't have a voice in the country anymore so what are you going to do?"

Sorbo appeared in the highly successful Christian film "God's Not Dead" – playing an atheist professor whose beliefs are challenged by a Christian student.

"I'm a Christian myself and had to play an atheist," he said. "I see the anger of these (atheist) guys on TV and it's like 'Wow, how do you get so angry at something you don't believe in?"

The "Hercules" star also encouraged tolerance between believers and nonbelievers.

"What's interesting is that people say students don't get persecuted in universities because of their beliefs but it does happen," Sorbo explained. "What's the big deal? I'm a 'live and let live' kind of guy. If you're an atheist, fine. If you're agnostic, we can talk. This movie is not to preach to the choir, we wanted the choir to come and obviously they did."

"God's Not Dead" was one of a series of religious films produced this year that were box office hits. "Noah" and "Son of God" were also commercially successful, and are being followed up quickly by other Bible-based projects.
