Excerpted from The Intrafaith Conversation:

Is a professed belief in Jesus Christ the only way to salvation? When Rob Bell published his book, Love Wins: A Book About Heaven, Hell, and the Fate of Every Person Who Ever Lived, in 2011, his answer in essence was “No.” Accusations of heresy immediately began to fly from Bell’s evangelical community.

Bell anticipated their criticism in the book:
As soon as the door is opened to Muslims, Hindus, Buddhists, and Baptists from Cleveland, many Christians become very uneasy, saying that then Jesus doesn’t matter anymore, the cross is irrelevant, it doesn’t matter what you believe, and so forth. Not true. Absolutely, unequivocally, unalterably not true.

Whether or not you agree with all of Rob Bell’s conclusions, he has certainly highlighted the challenge for Christians today as we come into contact with those of other  religious traditions (as well as many within our own).
