Not all religions can be all wrong and not all religions can be all right, and after devoting my life to philosophical study of all religions there is only one religion that asks you to question everything about that religion. That religion is Christianity and after doing that I have come to the conclusion that it is the only true and right religion. --Ravi Zacharias
Ravi Zacharias states that a coherent worldview must be able to satisfactorily answer four questions: that of origin, meaning, morality, and destiny. He says that while every major religion makes exclusive claims about truth, the Christian faith is unique in its ability to answer all four of these questions He routinely speaks on the coherency of the Christian worldview, saying that Christianity is capable of withstanding the toughest philosophical attacks. Zacharias asserts that the apologist must argue from three levels: the theoretical to line up the logic of the argument, the arts to illustrate, and "kitchen table talk" to conclude and apply.
