There are connections among the great revealed religions.
"People often say that religions are fundamentally the same and superficially different. May I reverse that for you and tell you that religions are fundamentally different and at times superficially similar. If I am asked what separates Christianity from other religions, or “what’s different about Christianity, aren’t all religions the same when you get down to it,” one of the first things that I would say is bound up in one beautiful word: forgiveness."
-Ravi Zacharias
