Christian teacher and bestselling author Francis Chan is challenging the notion that hell is not forever and that a loving God couldn't punish someone for eternity.

Well-known pastor Rob Bell recently came under fire for questioning the Church's teachings on heaven and hell in his book, Love Wins.

Bell, who several critics accused of being a universalist after his book's release, argued that the idea that all non-Christians will be punished in hell is "misguided and toxic."

Chan responds to Bell's position with his own biblical studies in his new book, Erasing Hell: What God Said About Eternity and the Things We've Made Up.

He warns that being "careless" with God's word can be dangerous, especially when it comes to difficult questions like the existence of heaven and hell.

"I've been concerned as I've listened to some of the discussion about hell," Chan said in a YouTube video promoting his book.

"We can't just have these theological discussions about a doctrine when we're talking about people's eternal destinies here," he said.

"We've got to lay everything on the table," he continued. "I want to just present all of the facts, everything I can think of in this book (the Bible) and let you decide -- not sway you."

Chan says Bell's book "got the ball rolling" on his "sobering" study of hell.

"There's so many emotions that run through me whenever I even say the word hell. So, I think it's healthy, and it's good for my soul to discuss and to study," Chan told Relevant Magazine. "But it's very difficult. It's always difficult."

Chan said his book welcomes discussion but that it be done "with humility."

Erasing Hell is set to release July 5.
